Subject: virtManager: ignore agen livecycle event for shutoff VMs

This event is mainly to refresh the VM XML to figure out the state of
virtio channels and that should happen only for running VMs.

This affects external snapshot behavior in virtManager. If the VM is
offline and user deletes external snapshot libvirt needs to start QEMU
process to delete the snapshot. The QEMU process is started with stopped
CPUs so it is visible as online and paused. It also emits the agent
lifecycle event but there is no other domain lifecycle event so after
the snapshot deletion the VM stays paused in virtManager even if it is
already offline in libvirt.

To mitigate this behavior we can ignore agent lifecycle event for
shutoff VMs.
