[ 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.
