[llvm] [offload] [test] Use test compiler ID rather than host (PR #124408)

[Michał Górny via llvm-commits]

https://github.com/mgorny created https://github.com/llvm/llvm-project/pull/124408

Use the test compiler ID to verify whether tests can be run rather than the host compiler.  This makes it possible to run tests (with Clang) while the library itself was built with GCC.
