Keybase needs to use user namespaces, hence it needs an unconfined
profile when user namespaces are restricted from unconfined like other
applications in MR #1123https://gitlab.com/apparmor/apparmor/-/merge_requests/1123
In addition this serves as a handle to uniquely identify keybase
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.
