Eugene Syromiatnikov bebabb191d Add zstd kmod compression support
* brp-kmod-restore-perms: Add chech for "$RPM_BUILD_ROOT/$path.zst".
* find-provides.ksyms: Add "\.zst" to the kernel module path matching
regular expression; process kernel module with zstd if its file name
ends with "zst".
* find-requires.ksyms: Likewise.
* firmware.prov: Add "\.zst" to the kernel module path matching
regular expression.
* kmodtool (%post, %preun): Likewise.
* modalias.prov: Likewise.
* modalias.attr (%__modalias_path): Add "ko\.zst" to the kernel module
path matching regular expression.
* provided_ksyms.attr (%__provided_ksyms_path): Likewise.
* required_ksyms.attr (%__required_ksyms_path): Likewise.
* kmod.attr (%__kmod_path): Add ".*\.ko\.zst" to the kernel module path
matching regular expression.
(strip_compress_sfx): Strip "\.zst" suffix, if present.
