apparmor: Enable tuning of policy paranoid load for embedded systems
AppArmor by default does an extensive check on loaded policy that
can take quite some time on limited resource systems. Allow
disabling this check for embedded systems where system images are
readonly and have checksumming making the need for the embedded
policy to be fully checked to be redundant.
Note: basic policy checks are still done.
