[pkg-lighttpd] Bug#838473: lighttpd: Not reliably stoppable using systemd service file

[Lukas Martini]

Package: lighttpd
Version: 1.4.35-4+deb8u1
Severity: normal

When running 'systemctl stop lighttpd', sometimes the command will seemingly
complete successfully, but doesn't actually stop lighttpd. Similarly, after
'systemctl restart lighttpd' the same instance will just continue running
(as the old one isn't stopped and systemd's attempt to start lighttpd
again obviously fails as the ports are in use).

I haven't properly debugged this issue in any way, but I've seen it across
various servers using lighttpd. My first guess for the cause would be 
that no pidfile is specified in the systemd service and systemd is left guessing
for the main task, but I could be wrong.
