cups: whitelist CVE-2018-6553

This an Ububtu specific issue:

The CUPS AppArmor profile incorrectly confined the dnssd backend
due to use of hard links. A local attacker could possibly use this
issue to escape confinement. This flaw affects versions prior to
2.2.7-1ubuntu2.1 in Ubuntu 18.04 LTS, prior to 2.2.4-7ubuntu3.1
in Ubuntu 17.10, prior to 2.1.3-4ubuntu0.5 in Ubuntu 16.04 LTS,
 and prior to 1.7.2-0ubuntu1.10 in Ubuntu 14.04 LTS
