[Driver] Fix Arm/AArch64 Link Argument tests (#144582)

The openmp-offload-amdgpu-runtime-2 bot specifies default rtlib of
compiler-rt, but default unwindlib of libgcc. Change the tests to accept
that there may be `"--as-needed" "-lgcc_s" "--no-as-needed"` between
`libclang_rt.builtins.a` and `-lc`.

Relates to #121830
