Don't list /lib/modules/$KernelVer/kernel twice
For quite some time I see warnings like
warning: File listed twice: /lib/modules/[...]/kernel
when building the kernel-core rpm. This is because that directory is included
both in module-dirs.list (and therefor in, basically, kernel-core.list) and in
Tweak the find command that generates module-dirs.list so that this directory
is not included in that list anymore.
