This batch of tests adds a fake topology on which each numa node
has multiple sockets. We didn't find yet a real HW topology in the wild
like this, but we need one to fully exercise the code.
So, until we find a HW topology, we add a fake one flipping
the NUMA/socket config of the existing xeon dual gold 6320.
