Backport fix for CVE-2026-11721 to bind 9.11 on c8s. The patch
combines two upstream commits (06778424f0 and e5b16cfd1c) that
prevent dnssec-signzone from signing out-of-zone records and
reject RRSIG records whose labels field indicates fewer labels
than the signer name requires, closing a cache poisoning vector
via forged wildcard records.
