Reword address format definition in section 4.5
Let's refrain from mentioning section 6.4 in here, as the format
is not exactly the same - not all address type field values from
section 6.4 make sense in NETINFO cell and NETINFO cell does not
have a TTL value at the end of each address. It's a little confusing
to suggest that there is a reuse of wire format fragment between
RELAY_RESOLVED and NETINFO cells.
