When we return the full RR wire data, let's make sure the TTL included in it is adjusted by the time the RR sat in the cache. As an optimization we do this only for ResolveRecord() and not for ResolveHostname() and friends, since adjusting the TTL means copying the RR object, and we don#t want to do that if there's no reason to. (ResolveHostname() and friends don't return the TTL hence there's no reason to in that case)
