bhyvexml2argvmock: Provide virCPUProbeHost()

The bhyvexml2argvmock is loaded by bhyvexml2argvtest which calls
virBhyveCapsBuild() which in turn calls virCPUProbeHost(). To
make our test environment stable, it shouldn't depend on actual
CPU and thus mocked implementation for virCPUProbeHost should be
offered. Surprisingly, this is done in bhyveargv2xmlmock but not
in bhyvexml2argvmock. Until now.
