Explicitly kill all k3s containers at system shutdown

Put the file in /etc/systemd/system/shutdown-k3s.service and then enable the service using

systemctl enable shutdown-k3s.service

Also note that this service name shutdown-k3s must not start with k3s-, otherwise the k3s-killall.sh script would also try to stop this service and cause problems.
