Fix TTL issue with ANY queries processed through RPZ "passthru"

Browse Source 
Answers to an "ANY" query which are processed by the RPZ "passthru"
policy have the response-policy's 'max-policy-ttl' value unexpectedly
applied. Do not change the records' TTL when RPZ uses a policy which
does not alter the answer.

(cherry picked from commit 5633dc90d3)
