script: Set libvirt defaults to not stop containers on exit
script: Set libvirt defaults to not stop containers on exit

libvirt's upstart job has a pre-stop stanza which kills all VMs using
the URIs in `libvirt_uris`, but flynn-host needs to know what containers
are running when it is shutting down so it knows what to resurrect when
it starts again, so override `libvirt_uris` to not contain `lxc:///`.
