qemu: Don't use CPU from host capabilities as host-model on ARM
qemu: Don't use CPU from host capabilities as host-model on ARM

We never supported host-model CPUs on ARM and we don't want to support
them even once patches for direct detection of host CPU are merged. And
since using host CPU definition for host-model CPUs exists only for
backward compatibility, we should not use it for any host-model support
added in the future. Such enhancement should exclusively use the result
of query-cpu-model-expansion. Until proper host-model support is
implemented for ARM (if ever), we need to make sure the detected host
CPU is not accidentally used for host-model CPUs.
