Subject: 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.
