Test that an expired RRset does not block negative caching

Cover the inverse of the CD=1 NXDOMAIN guard: a validated RRset that
has passed its TTL, but has not yet been cleaned from the cache, must
not block the unvalidated negative entry. Before the fix the CD=1
query failed with SERVFAIL until the expired header was reaped.
