Title:
  mantic kernel 6.5.0.1006 Adds io_uring apparmor feature

Status in livecd-rootfs package in Ubuntu:
  Fix Released

Bug description:
  starting with kernel package(s) 6.5.0.1006, currently in mantic-
  proposed, `io_uring` is added as a apparmor feature. This change
  results in preseeded snaps being unoptimized, as the mounted apparmor
  features in the chroot do not match the 6.5.0.1006 kernels. On a
  system running with the kernel

  cat /sys/kernel/security/apparmor/features/io_uring/mask
  sqpoll override_creds

  1. ensure that this is correct with kernel and security teams
  2. ~~ensure that this is the default going forward~~  : Create a 6.5 feature directory as it was pointed out by xnox that Mantic has more than 6.5 kernels at this time.

  if 1 and 2, then set the default in `livecd-rootfs` for mounted
  apparmor features to include io_uring
