s390x/cpumodel: let the CPU model handle feature checks
If we have certain features enabled, we have to migrate additional state
(e.g. vector registers or runtime-instrumentation registers). Let the
CPU model control that unless we have no "host" CPU model in the KVM
case. This will later on be the case for compatibility machines, so
migration from QEMU versions without the CPU model will still work.
