Subject: [PATCH] Allow skipping the build of kernel-headers package

When a newer kernel branch is published into the official repositories,
its kernel-headers, cpupower, perf anf kernel-doc packages will be used
instead. One could turn off building of the last three, but there was no
such switch for kernel-headers. Add it.
