S390: Enable -cpu help and QMP query-cpu-definitions

Browse source 
This enables qemu -cpu help to return a list of supported CPU models
on s390 and also to query for cpu definitions in the monitor.
Initially only cpu model = host is returned. This needs to be reworked
into a full-fledged CPU model handling later on.
This change is needed to allow libvirt exploiters (like OpenStack)
to specify a CPU model.
