[rt] Remove xen-linux-system packages and references to Xen support

It is not sensible to run a PREEMPT_RT kernel under Xen or any other
hypervisor that doesn't itself provide real-time scheduling.

This requires reintroducing an explicit 'none' featureset for amd64
and i386, just to hold the Xen support definitions.
