dnsdist: Drop queries with no question (qdcount == 0)

Added a counter for these dropped queries, `emptyQueries` too.
This might be an issue for DNS cookies some day, as it uses
query with no question [1].
Additionnaly drops queries with QR set over TCP too to be
consistent with UDP.
This might close #3290.
