Make interface spec optional in --auth-server.

Browse Source 
But make auth-server required when any auth-zones are defined.

The "glue record" field in auth-server is needed to synthesise
SOA and NS records in auth zones, so the --auth-server has to
be specified. If makes sense, however to define one or more
auth-zones that appear within the normal recursive DNS service
without actually acting as an authoritative DNS server on
any interface. Hence making the interface field optional.
