This pull request fixes the nix devshell on Darwin systems by making jemalloc and liburing only added as an input on Linux, supersedes #1608. This PR also makes nix build work to build a binary on darwin by skipping the patchelf step on Darwin, and fixing the platforms meta attribute.

Pull request checklist:

• This pull request targets the main branch, and the branch is named something other than
  main.
• I have written an appropriate pull request title and my description is clear.
• I understand I am responsible for the contents of this pull request.
• I have followed the contributing guidelines:
  • My contribution follows the code style, if applicable.
  • I ran pre-commit checks before opening/drafting this pull request.
  • I have tested my contribution (or proof-read it for documentation-only changes)
    myself, if applicable. This includes ensuring code compiles.
  • My commit messages follow the commit message format and are descriptive.
  • I have written a news fragment for this PR, if applicable.

Your PR title is a short, single sentence describing what you changed 2. You have described in more detail what you have changed, why you have changed it, what the intended effect is, and why you think this will be beneficial to the project. If you have made any potentially strange/questionable design choices, but didn't feel they'd benefit from code comments, please don't mention them here - after opening your pull request, go to "files changed", and click on the "+" symbol in the line number gutter, and attach comments to the lines that you think would benefit from some clarification. --> This pull request fixes the nix devshell on Darwin systems by making jemalloc and liburing only added as an input on Linux, supersedes #1608. This PR also makes `nix build` work to build a binary on darwin by skipping the patchelf step on Darwin, and fixing the `platforms` meta attribute. <!-- Example: This pull request allows us to warp through time and space ten times faster than before by double-inverting the warp drive with hyperheated jump fluid, both making the drive faster and more efficient.

Please do not open a PR if all you have done is asked ChatGPT to tidy up the codebase with a +-100,000 diff. - In the case of code style violations, reviewers may leave review comments/change requests indicating what the ideal change would look like. For example, a reviewer may suggest you lower a log level, or use `match` instead of `if/else` etc. - In the case of code style violations, pre-commit check failures, minor things like typos/spelling errors, and in some cases commit format violations, reviewers may modify your branch directly, typically by making changes and adding a commit. Particularly in the latter case, a reviewer may rebase your commits to squash "spammy" ones (like "fix", "fix", "actually fix"), and reword commit messages that don't satisfy the format. - Pull requests MUST pass the `Checks` CI workflows to be capable of being merged. This can only be bypassed in exceptional circumstances. If your CI flakes, let us know in matrix:r/dev:continuwuity.org. - Pull requests have to be based on the latest `main` commit before being merged. If the main branch changes while you're making your changes, you should make sure you rebase on main before opening a PR. Your branch will be rebased on main before it is merged if it has fallen behind. - We typically only do fast-forward merges, so your entire commit log will be included. Once in main, it's difficult to get out cleanly, so put on your best dress, smile for the cameras! --> [c1]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md [c2]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/docs/development/code_style.mdx [c1pc]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#pre-commit-checks [c1t]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#running-tests-locally [c1cm]: https://forgejo.ellis.link/continuwuation/continuwuity/src/branch/main/CONTRIBUTING.md#commit-messages [n1]: https://towncrier.readthedocs.io/en/stable/tutorial.html#creating-news-fragments

Since I don't have a darwin/macos system, myself, I'd greatly appreciate if someone else is able to test this.
Otherwise, I can spin up a VM, but it would be nice for someone to test on regular macos.

To be honest, this can also be merged without testing, it doesn't affect Linux, and certainly makes MacOS closer to building than it would be otherwise, so it can be merged and further changes can be made later.
