Bump wait time in servestale test with 1 second

This check intermittently failed:

I:serve-stale:check not in cache longttl.example times out...
I:serve-stale:failed

This corresponds to this query in the test:

$DIG -p ${PORT} +tries=1 +timeout=3  @10.53.0.3 longttl.example TXT

Looking at the dig output for a failed test, the query actually got a
response from the authoritative server (in one specific example the
query time was 2991 msec, close to 3 seconds).

After doing the query for the test, we enable the authoritative
server after a sleep of three seconds. If we bump this sleep to 4
seconds, the race will be more in favor of the query timing out,
making it unlikely that this test will fail intermittently.

Bump the subsequent wait_for_log checks also with one second.
