[pkg-apparmor] Bug#845232: Maybe add README.Debian

[Lisandro Damián Nicanor Pérez Meyer]

Package: apparmor-notify
Version: 2.11.1-3
Followup-For: Bug #845232

I had the same issue. 

= What did I do

At first I found the .desktop file and run the
command by hand. I learnt that I would nee dto read /var/log/kern.log,
so I added my user to the adm group.

After that I restarted my session and learn that I would need to be in
the sudo group.

= What I recommend

Adding a README.Debian file explaining this details. That's the first
thing I tried to find when I noticed aa-notify was not working.

Thanks!!
