apparmor: improve overlapping domain attachment resolution
Overlapping domain attachments using the current longest left exact
match fail in some simple cases, and with the fix to ensure consistent
behavior by failing unresolvable attachments it becomes important to
do a better job.
eg. under the current match the following are unresolvable where
the alternation is clearly a better match under the most specific
left match rule.
/**
/{bin/,}usr/
Use a counting match that detects when a loop in the state machine is
enter, and return the match count to provide a better specific left
match resolution.
