Subject: [PATCH] Add support for kernel module compression
This adds the support for kernel module compression in
pesign-obs-integration infrastructure. The kernel-binary spec needs
to pass $BRP_PESIGN_COMPRESS_KERNEL for enabling the compression.
Currently only "xz" is supported.
pesign-gen-repackage-spec received a new option --compress, which is
passed from pesign-repackage.spec, where brp-99-pesign enables it per
the variable above.
With --compress option, pesign-gen-repackage-spec script just
compresses the kernel object at the last repackaging phase.
