apparmor-utils-tests: replace dependency on 'aa-status' by 'apparmor'

aa-status was merged back in apparmor in 3d5b5245 during the bookworm rebase because the reason of the split was no longer valid. Unfortunately, the dependency of apparmor-utils-tests was not updated. apparmor-utils-tests is not installable and makes tests failing with messages like:

apparmor-utils-tests : Depends: aa-status but it is not installable
...
Unable to start stage 1. Read the log for more details.
