pppoe: T1318: use systemd to manage connection
This reduces the amount of self written code to start-stop-daemon and also kill the process if it has no connection yet (there won't be a PID file in this case) and getting the proper PID for multiple processes would require me to walk the /proc/<pid>/cmdline for every binary involved.
