s390x/kvm: move KVM declarations and stubs to separate files
Let's do it just like the other architectures. Introduce kvm-stub.c for stubs and kvm_s390x.h for the declarations. Change license to GPL2+ and keep copyright notice. As we are dropping the sysemu/kvm.h include from cpu.h, fix up includes.
