  [test][clang][driver] Fix test that assumes libomp default (#119319)

755519f7f661375be05750001ff11e106e6b7f87 added a test that uses
`-fopenmp`. The default configuration of CLANG_DEFAULT_OPENMP_RUNTIME is
libomp, which causes `-fopenmp` to act as `-fopenmp=libomp`. In turn,
this passes `-fopenmp` to downstream compilations. However, for other
values, e.g. `libgomp`, Clang does not know how to generate useful
openmp code, so it avoids passing the `-fopenmp` along. Fix the test to
explicitly pass `-fopenmp=libomp` to pass regardless of the configured
CLANG_DEFAULT_OPENMP_RUNTIME value.
