[libunwind] [libunwind] Make Apple OS version XFAILs robust to patch-level versions (PR #218125)

[Louis Dionne via cfe-commits]

https://github.com/ldionne created https://github.com/llvm/llvm-project/pull/218125

We are seeing some failures since some of the Apple CI runners have been updated to 26.5.2. That was caused by the regular expressions not matching patch level version bumps.
