Fix bug #6805, fix handling nets-host-mtu in more contexts like resume
from hibernation and printing the commandline of a snapshot. Disallow
setting that property by a user via API like is done for other
VM-state properties.

Sorry, I thought I had checked for all occurences of 'runningmachine'
when introducing 'running-nets-host-mtu', but apparently I missed some
in the QemuServer module :(

Also introduce proper privilege checking for VM-state properties.

Finally, detect and cleanup such properties upon VM start.

I haven't come around to testing these for stable-bookworm yet, but
will let you know if they apply/work cleanly there too.
