[apparmor] [PATCH 6/8] Remove dead code around pattern matching in rules

[Tyler Hicks]

From: John Johansen <john.johansen at canonical.com>

remove old dead code that used to fail compilation if regular expressions
where detected in the rules and the apparmor kernel module did not support
regular expression matching.
