Carlos Santos 3c6a5bdd3e netplug: prevent starting multiple instances of netplugd
Executing "/etc/init.d/S29netplug start" multiple times resulted in
multiple instances of netplugd.

Pass "-p /var/run/netplug.pid" to netplugd, so it creates the PID file
that start-stop-daemon needs to know that netplugd is already running.
Also use the pid file to stop netplugd, instead of the daemon name.
