[clang][AIX] Remove test for the default OpenMP runtime

[• pcwang-thead]

Summary

The default OpenMP runtime may not be libomp since it can be changed
by specified CLANG_DEFAULT_OPENMP_RUNTIME. This test will fail if
we change the default OpenMP runtime.

This patch removes test for the default OpenMP runtime and moves the
CHECKs downward.
