enable parallel xz compression of modules
So this uses the -P option for xargs to allow parallel compression
of xz uaing xargs options, it allows maximum usage of available CPUs
it can be reverted to the prior status quo but running the following
sed -i 's/global zcpu `nproc --all`/global zcpu 1/' kernel.spec
