CLEANUP: config: improve address parser error report for unmatched protocols

Just trying "quic4@:4433" with USE_QUIC not set rsults in such a cryptic
error:

   [ALERT]    (14610) : config : parsing [quic-mini.cfg:44] : 'bind' : unsupported protocol family 2 for address 'quic4@:4433'

Let's at least add the stream and datagram statuses to indicate what was
being looked for:

   [ALERT]    (15252) : config : parsing [quic-mini.cfg:44] : 'bind' : unsupported stream protocol for datagram family 2 address 'quic4@:4433'

Still not very pretty but gives a little bit more info.
