[llvm] Fix test added in #155148 work with Windows style path separators. (PR #155354)

[via llvm-commits]

https://github.com/dyung created https://github.com/llvm/llvm-project/pull/155354

Should fix Windows build bot failures such as https://lab.llvm.org/buildbot/#/builders/46/builds/22281.

The test (and the followup fix in #155303) did not properly account for Windows style path separators.
