ch_monitor: Kill the cloud-hypervisor procees on monitor close

commit c857ac8 modified the VM creation by converting the
cloud-hypervisor as a daemon there by reparenting to init. So
we can no longer use virProcessAbort as it assumes that the
process to be killed is a child.

So use virProcessKillPainfully instead.
