[pkg-apparmor] Bug#870697: Please provide systemd service file which doesn't require the SysV init script

Sure!

Even though currently this bug affects Debian/Ubuntu-specific code,
this problem is being (slowly!) researched/discussed upstream, because
we would like something that works cross-distro as much as possible:
currently Debian/Ubuntu use a custom initscript and support library,
while openSUSE uses the initscript shipped in the upstream tarball
IIRC; the switch to a native systemd service file is a great
opportunity to finally end this nonsense and share more code between
distros :)
