MINOR: dns: query type change when last record is a CNAME

DNS servers don't return A or AAAA record if the query points to a CNAME
not resolving to the right type.
We know it because the last record of the response is a CNAME. We can
trigger a new query, switching to a new query type, handled by the layer
above.
