apparmor: Fix regression in profile conflict logic
The intended behaviour in apparmor profile matching is to flag a conflict if two profiles match equally well. However, right now a conflict is generated if another profile has the same match length even if that profile doesn't actually match. Fix the logic so we only generate a conflict if the profiles match.
