    fix: test: Make the dns64/filter-a reentry test trigger the crash

    The cached NODATA for the AAAA query lived for the SOA's 60-second
    TTL, so it never expired before the A answer arrived and filter-a never
    re-queried AAAA: the test passed with the fix reverted.

    The A answer, delayed by two seconds, also outlasted the resolver's
    retry timeouts.  It was only accepted when a backed-off retry happened
    to cover the delays of the earlier queries queued ahead of it on the
    same TCP connection; on a slow runner none did and the query timed out.

    Give the NODATA a one-second TTL and leave the first two A queries
    unanswered instead.  The test now also checks that filter-a queries
    AAAA again, so that it fails rather than passes without exercising the
    bug if the resolver's retry timing ever changes.
