utils: Add aa-remove-unknown utility to unload unknown profiles

https://launchpad.net/bugs/1668892

This patch creates a new utility, with the code previously used in the
init script 'restart' action, that removes unknown profiles which are
not found in /etc/apparmor.d/. The functionality was removed from the
common init script code in the fix for CVE-2017-6507.

The new utility prints a message containing the name of each unknown
profile before the profiles are removed. It also supports a dry run mode
so that an administrator can check which profiles will be removed before
unloading any unknown profiles.

If you backport this utility with the fix for CVE-2017-6507 to an
apparmor 2.10 release and your backported aa-remove-unknown utility is
sourcing the upstream rc.apparmor.functions file, you'll want to include
the following bug fix to prevent the aa-remove-unknown utility from
removing child profiles that it shouldn't remove:

  r3440 - Fix: parser: incorrect output of child profile names
