Bug description:
  Preseeding with the HWE 6.14 kernel fails due to AppArmor feature
  mismatch.

  [ Impact ]

  When building Ubuntu images with the HWE 6.14 kernel using livecd-
  rootfs, snap preseeding fails since there is a mismatch between the
  kernel's AppArmor capabilities and the capabilities listed in livecd-
  rootfs. As a result, these images have slower boot times as snaps are
  being seeded at first boot instead of image creation.

  [ Test Plan ]

  * Build an image with livecd-rootfs
  * Register the image on the cloud
  * Boot into the image
  * Check that "snap debug seeding" output doesn't contain the "seed-restart-system-key" key. Otherwise, check the `seed-restart-system-key` to see what features are missing.

  [ Where problems could occur ]

  The risk of regressions is minimal since we have previously backported
  similar changes a couple of times, and there should not be any runtime
  changes for end-users. One potential problem is if the proposed
  changes do not properly rectify the mismatch in the AppArmor features,
  which will cause the slow boot times to remain.
