Currently, weston tests fail when using systemd, fix it by providing
transient unit file and inject it via systemd-run, which generates a
service file automatically and launches another weston instance to test
if it can launch a nested instance. Use systemctl stop to end the
service and cleanup, instead of brutal kill
