runstate: Allow user to migrate twice

It should be a matter of allowing the transition POSTMIGRATE ->
FINISH_MIGRATE, but it turns out that the VM won't do the
transition the second time because it's already stopped.

So this commit also adds vm_stop_force_state() which performs
the transition even if the VM is already stopped.

While there also allow other states to migrate.
