s390x: change the QEMU cpu model to a stripped down z12
We are good enough to boot upstream Linux kernels / Fedora 26/27. That should be sufficient for now. As the QEMU CPU model is migration safe, let's add compatibility code. Generate the feature list to reduce the chance of messing things up in the future.
