Subject: [PATCH] Drop file-rc support

file-rc used to be the init system up and until including Grml stable
release 2014.11, starting with beginning of 2016 Grml switched to
systemd instead.

The last Debian release that used to have file-rc available was
Debian/stretch, which is EOL and we don't support it neither anymore.
So, good riddance!
