kernel.spec: xz compress modules on i686 and x86_64
Pretty grody, but it seems to be working... it has to happen after
module signing (obviously) and after find-debuginfo.sh runs as well, so
tacking it onto the end seems sensible, and then just fixing up the file
lists as we go. Provides a nice tidy savings to the disk footprint:
kyle@dreadnought:~% for i in kernel-core-3.15.0-0.rc3.git4.1.fc21.x86_64.rpm \
kernel-core-3.15.0-0.rc3.git4.1.fc21.x86_64.rpm.1; do \
rpm -qip $i | grep '^Size'; done
Size : 43011603
Size : 81106737
kmod has handed .xz and .gz modules for a long time now, and can cope.
I was thinking we might also %ghost the .ko, and have a %post install
script that un-xz the modules in /proc/modules, but none of them are big
enough for that to be worthwhile I think (maybe XFS, but I doubt it.)
