The reason to write the patch: I'm lazy ;-)

Someone on the opensuse-de mailinglist asked about apparmor desktop 
notifications, and I told him to use "sudo aa-notify -p --display $DISPLAY".
The response was: "I only get the error message '$user must be in admin 
group'", so I had to write another mail.

With the enhanced error message, it will be obvious what needs to be 
done. That's more user friendly and also means I have to answer less
mails ;-)

Good point.
