In sudo when the category is all do not allow members, and vice versa.

This is what we already do in the HBAC plugin, this ports it to Sudo.

If a category (user, host, etc) is u'all' then we don't allow individual
members be added. Conversely if there are members we don't allow the
category be set to u'all'.
