3b30e917e8 Fix CVE-2026-11721: reject RRSIG records with invalid label counts
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.

CVE: CVE-2026-11721
Upstream patches:
 - 06778424f0.patch
 - e5b16cfd1c.patch
Resolves: RHEL-213407
