[libvirt] [PATCH 09/27] tests: Add test infrastructure for qemuMonitorGetCPUInfo

As the combination algorithm is rather complex and ugly it's necessary to make sure it works properly. Add test suite infrastructure for testing it along with a basic test based on x86_64 platform. --- ...nitorjson-cpuinfo-x86-basic-pluggable-cpus.json | 50 ++++++++
