Subject: [PATCH] kmod.attr: add compressed kmod support

* kmod.attr (%__kmod_path): Add ".*\.ko\.gz|.*\.ko\.bz2|.*\.ko\.xz"
to he module path matching regular expression endings.
(%__kmod_provides) <strip_compress_sfx>: New function.
(%__kmod_provides): Generate dependencies with module file name without
compressed extension (just ".ko") for compressed modules.
