[libvirt] [PATCH 30/33] cputest: Test virQEMUCapsInitCPUModel



The original test didn't use family/model numbers to make better
decisions about the CPU model and thus mis-detected the model in the two
cases which are modified in this commit. The detected CPU models now
match those obtained from raw CPUID data.
