* hypervisor_cpu_model: enable on x86_64

Add config for x86_64.

* hypervisor_cpu_model: enable aarch64

Add config to enable aarch64 coverage.

* fix libvirt_version check

Config was available but forgot to check version in code with that
config.

* cfg: remove unused parameters

Initially this configuration was reused from a similar test case.
However, these parameters are not necessary anymore.
