[libcxx-commits] [libcxx] [libc++] XFAIL regex tests that are currently failing on macOS (PR #159260)

[Nikolas Klauser via libcxx-commits]

https://github.com/philnik777 created https://github.com/llvm/llvm-project/pull/159260

It seems that an OS update changed the localization on macOS. This XFAILs the tests to make sure the CI is green again until the tests can be updated.
