Title:
  AppArmor profiles missing for jammy and 6.8 kernel

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Jammy:
  Fix Released

Bug description:
  A CPC test build of a jammy image with 6.8 edge kernel revealed that
  AppArmor profiles are missing for 6.8 kernel in livecd-rootfs, leading
  to fall back to generic AppArmor profiles which don't contain
  configuration for io_uring. This leads to `snap debug seeding` output
  non-empty `seed-restart-system-key` dict (attached in snap-debug-
  seeding.json) after first boot.

  [ Impact ]

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

  [ Test Plan ]
  * Build a jammy cloud image with preseeded snaps with the 6.8 edge 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 "io_uring"

  [ 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 will block jammy image
  publication once the edge kernel becomes the HWE kernel.
