Peter Dillinger 9577b92b55 Fix ODR violation from open source folly build, update (#14094) 
Summary:
Following up on https://github.com/facebook/rocksdb/pull/14071, updating folly to
8a9fc1e80a or beyond was failing an F14Table assertion for a very subtle reason: ODR violation between the folly build and RocksDB build because folly build was release mode and RocksDB build was debug mode. What was happening was that folly change introduced a dependence on kDebug (whether build is debug) in a hashing implementation in a .h file, and the inconsistency between the inlined implementation during RocksDB build and the linked-to implementation from the folly build was leading to inconsistencies in the data structure.

The primary fix is to ensure we build folly in debug mode for debug mode RocksDB builds. Also,

* Needed to use the `patchelf` tool in `build_folly` to ensure the glog dependency shared library can always find its own gflags dependency. I explored many options for working around this, and this is what would work without reworking folly's own build.
* Updated folly to latest commit.
* Thrown in an ad hoc folly patch to use ftp.gnu.org mirrors (the canonical is super slow)
* Moved the placement of GETDEPS_USE_WGET=1 to apply to local builds also, to avoid the issue of a large download almost reaching completion and then stalling indefinitely.
* Fix failing nightly build-linux-cmake-with-folly-lite-no-test with fmt includes in cmake build (as was done with make build)
* Add a release mode folly+RocksDB to nightly CI, including both cmake and make. This also serves as a non-cached folly build to detect potential problems with PR jobs working from cached folly build.
* Move build-linux-cmake-with-folly to nightly because it's mostly covered by build-linux-cmake-with-folly-coroutines

Intended follow-up:
* folly-lite build with tests
* Make the folly build caching more friendly+accurate by hashing the relevant Makefile parts and tagging whether debug or release. Not in this PR because then you wouldn't be able to see what changed in the folly build steps themselves.

# 2. Once installed, add the include path for gflags to your CPATH env var and
