resolved: also collect statistics about negative DNSSEC proofs

Browse Source 
We already maintain statistics about positive DNSSEC proofs, and count them up by 1 for each validated RRset. Now,
update the same counters each time we validated a negative query, so that the statistics are the combined result of all
validation checks, both positive and negative.
