LOG: Updating test clang/test/Driver/driverkit-path.c for usage with CLANG_RESOURCE_DIR (#197154)

When the CMake option CLANG_RESOURCE_DIR is specified, it changes 
the path to various tools and thus breaks some tests that look for things
in the "standard" location. This change updates one of the tests to take
into account the CLANG_RESOURCE_DIR value if specified by querying
compiler using `-print-resource-dir` to more accurately find the expected
directory in tests.
