perf tests kmod-path: Don't fail if compressed modules aren't supported

__kmod_path__parse() uses is_supported_compression() to determine and
parse out compressed module file extensions. On systems without zlib,
this test fails and __kmod_path__parse() continues to strcmp "ko" with
"gz". Don't do this on those systems.
