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.

Eugene Syromiatnikov 9a84b5ba8e brp-kmod-restore-perms: handle kmod compression done in post-install hooks 
If a kernel module are compressed by a post-install hook, then its name
would differ from the one saved by brp-kmod-set-exec-bit;  try to
recover from this by guessing a possible name of the compressed kmod and
using it instead.

* brp-kmod-restore-perms (while read perm path): Check for
"$RPM_BUILD_ROOT/$path.gz", "$RPM_BUILD_ROOT/$path.bz2",
and "$RPM_BUILD_ROOT/$path.xz" if "$RPM_BUILD_ROOT/$path"
does not exist, add the respective suffix to the $path.

Eugene Syromiatnikov 711c0be6ea Enable extraction of debug information for kmods 
This hack temporary adds executable permission for the *.ko files
during post-install stage so they are picked up by find-debuginfo.sh.
Since the intention is to avoid changing of behaviour in non-kmod
workloads, it's done by adding two additional brp-* scripts to the
__spec_install_post macro when kernel_module_package is instantiated.

* brp-kmod-restore-perms: New file.
* brp-kmod-set-exec-bit: Likewise.
* macros.kmp (%__brp_kmod_set_exec_bit, %__brp_kmod_restore_perms,
%__kmod_brps_added): New macros.
(%kernel_module_package): Rewrite __spec_install_post macro.
* redhat-rpm-config.spec (Source701, Source702): Add
brp-kmod-restore-perms and brp-kmod-set-exec-bit.
(Requires): Add find requirement for brp-kmod-set-exec-bit.
(%files): Explicitly list brp-* scripts for redhat-rpm-config and
kernel-rpm-macros packages.
