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

From: Kim Phillips <kim.phillips@arm.com>


[ Upstream commit 805b151a1afd24414706a7f6ae275fbb9649be74 ]

__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.
