[Apparmor-dev] [rfr] fixes for mandatoray profile HINT bug and empty config bug

[Dominic Reynolds]

Attach patch addresses two problems:

Mandatory Profile Missing - this case emits two messages the second of which
is an exec hint that I was adding to the log tree uneccessarily - and 
it should be ignored (and causes a bug) as the mandatory profile HINT
provides the needed information to create the new profile.


Empty config options - calls to find_first_(dir|file) are passed config
options as arguments. If these are null then an unintiialized value error
occurs. This patch adds a check for null arguments and just returns if they
are passed.
