  AppArmor profile policy `unconfined_restrictions` missing for jammy

Bug description:
  A CPC snap preseeding test failure on arm64 is blocking image pulication.
  A recent update, specifically 6.5.0.1017.17~22.04.1, to the jammy 6.5 kernel introduced a new AppArmor profile `unconfined_restrictions`. This is not reflected in the snap preseeding code and needs to be updated.

  [ Impact ]

  Boot will be slowed by ~200ms until this is resolved in livecd-rootfs

  [ Test Plan ]
  * Build a jammy and mantic cloud image with preseeded snaps with the 6.5.0 1017+ kernel
  * Boot an instance 
  * Invoke "snap debug seeding" 
  * Ensure the output does not include "seed-restart-system-key", if it does the difference between "preseed-system-key" and "apparmor-features"/"apparmor-parser-features" is other than "policy:unconfined_restrictions"

  [ Where problems could occur ]
  * If the attempted fix has problems "snap debug seeding" should continue to report "seed-restart-system-key". There should not be any other fallout.

  [  Other Info ]
  Public cloud images block image publication on a test ensuring that snaps are preseeded. As a result this bug is blocking jammy and mantic image publication.
