main, vmm: Remove guest_numa_node option from memory zones

The way to describe guest NUMA nodes has been updated through previous
commits, letting the user describe the full NUMA topology through the
--numa parameter (or NumaConfig).

That's why we can remove the deprecated and unused 'guest_numa_node'
option.
