[llvm] [llvm][.gitignore] macOS case-sensitive update (PR #177971)

[via llvm-commits]

https://github.com/tmjbios created https://github.com/llvm/llvm-project/pull/177971

If you run macOS on a case-sensitive file system,
.DS_store and .DS_Store are different files and the existing lowercase-s version doesn't match. Fix that.
