Code review comment for ~sergiodj/ubuntu/+source/apparmor:bug1872564-boot_id-rule-missing

Generally LGTM, I also added a focal task to the bug to later SRU it once groovy is fixed.

Changelog, patch headers and such look good.

The only thing that I found is that there was a follow on fix which IMHO should be included as well:
=> https://gitlab.com/apparmor/apparmor/-/commit/ef591a67cedc1da0676b26448ea96fa8c073c253
Due to that the state is "needs fixing", but other than this is already seems to be good.

Finally I'll add a review-slot for Ubuntu-security. That isn't strictly needed, but usually a good practice on security related changes.
