[libvirt] [PATCH v2] qemu: Honour <on_reboot/>

[Michal Privoznik]

https://bugzilla.redhat.com/show_bug.cgi?id=1476866

For some reason, we completely ignore <on_reboot/> setting for
domains. The implementation is simply not there. It never was.

diff to v1:
- dropped the spoofed logic
- Switch from qemuProcessShutdownOrReboot() to qemuPrcoessStop() because that's
  what <on_crash/> impl does too.
