Change serve-stale test stale-answer-ttl

Browse source 
Using a 'stale-answer-ttl' the same value as the authoritative ttl
value makes it hard to differentiate between a response from the
stale cache and a response from the authoritative server.

Change the stale-answer-ttl from 2 to 4, so that it differs from the
authoritative ttl.
