KVM: selftests: Pre-set threads affinity in hardware disable test when possible

Browse source

When building against a libc that provides pthread_attr_setaffinity_np(),
pre-set the grandchildren threads CPU affinity in the hardware disable test
to further reduce the perceived latency of pthread_create().  On large NUMA
systems, this reduces the average runtime from ~10s to ~5s.
