Support creating lock files on ExFAT on MacOS (#17115) 
## Summary

Fix #16859 by falling back to simply creating the lock file and then
attempting to apply permissions in cases where the temporary lockfile
cannot be renamed without overwriting (persist_noclobber) due to lack of
underlying support from the filesystem.

I've also improved the error handling.

## Test Plan

Manually on MacOS with an ExFAT partition.

~~~ bash session
$ hdiutil create -size 1g -fs ExFAT -volname EXFATDISK exfat.dmg
$ hdiutil attach exfat.dmg
$ cd /Volumes/EXFATDISK
$ uv init --bare --cache-dir build/uv/cache -v
