UBUNTU: SAUCE: (no-up) apparmor: fix mount not handling disconnected paths

upstream: No. This is a fix to an out of tree apparmor 3 patch

BugLink: http://bugs.launchpad.net/bugs/1496430
Mount rules are not honoring the attach_disconnected flag, causing
apparmor to deny mounts for lxc and docker even when the appropriate
rule exists in the profile.
