Subject: [PATCH] tests: Verify handling of CPU clusters in QMP data

Since aarch64 doesn't support CPU hotplug at the moment, we have
to get a bit creative.

While the 'query-cpus-fast' output is taken directly from a VM
configured as

the 'query-hotpluggable-cpus' output is constructed by hand
starting from the former and using the 'x86-dies' test data as
a model.
