[libvirt] [PATCH 2/2] S390: Enable the QMP query-cpu-definitions command

[Viktor Mihajlovski]

Since libvirt is using QMP for cpu definition probing, it is
beneficial to have a minimum implementation for that.
This covers only cpu model = host and needs to be reworked into
a full-fledged version later on.
