[clang] [clang][test] Specify value of `-fopenmp=libomp` for test. (PR #150301)

[Jordan Rupprecht via cfe-commits]

https://github.com/rupprecht created https://github.com/llvm/llvm-project/pull/150301

`libomp` is the default value when unconfigured in cmake, but llvm can be configured to have `libgomp` be the default instead. Explicitly specify this value so the test does not fail when it assumes libomp is always the default.
