Adding profiles for applications even if they allow all operations
will allow them to be referenced as peer by other policies. This is a
step towards a more comprehensive system policy, adding names, instead
of just unconfined, to peers of existing policy and to applications
that are known to use unprivileged user namespaces.

Note that unconfined mode should be changed for default_allow
when !1109

 is
merged.
