[PATCH v2 5/6] qemu_command: do use host-nodes for system memory

[Michal Privoznik]

After previous commit, it's no longer possible to change nodeset
for strict numatune. Therefore, we can start generating
host-nodes onto command line again.

This partially reverts d73265af6ec41104c20633b5c0a23688a62105e6.
