The #5872 reproducer plants a covering NSEC that is rejected inside the
cache (find_coveringnsec), so it never reaches the trust check on the
exact-match NODATA branch of query_coveringnsec(). This adds a companion
case: an NSEC owned by the victim name itself, injected at pending trust
via a CD=1 query, is returned by the cache as a NODATA proof for the
exact node and must not be used to synthesize a NODATA that would deny
the victim's real A record.
Reuses the f004.test fixture with a victim-owned forged NSEC.
