virQEMUCapsProbeHVF: Factor out setting of the capability

Browse Source 
Separate the architecture specific code to probe the support for HVF
from the actual setting of the capability.

In upcoming patches 'virQEMUCapsProbeHVF' will be mocked in the
testsuite to provide testing for the HVF hypervisor.
