These are profiles for applications that create user namespaces, both
the actual policy and unconfined profiles, like it was done in MR
1123.
https://gitlab.com/apparmor/apparmor/-/merge_requests/1123
In addition this serves as a handle to uniquely identify these
applications instead of unconfined to peers in policy.
Note that unconfined mode should be changed for default_allow when
https://gitlab.com/apparmor/apparmor/-/merge_requests/1109 is merged.
