Matthijs Mekking aaed7f9d8c Remove result exception on staleonly lookup
When implementing "stale-answer-client-timeout", we decided that
we should only return positive answers prematurely to clients. A
negative response is not useful, and in that case it is better to
wait for the recursion to complete.

To do so, we check the result and if it is not ISC_R_SUCCESS, we
decide that it is not good enough. However, there are more return
codes that could lead to a positive answer (e.g. CNAME chains).

This commit removes the exception and now uses the same logic that
other stale lookups use to determine if we found a useful stale
answer (stale_found == true).

This means we can simplify two test cases in the serve-stale system
test: nodata.example is no longer treated differently than data.example.
