openssh: set status for CVE-2026-3497

Analysis:
 - CVE-2026-3497 affects downstream OpenSSH GSSAPI Key Exchange patches.
 - The vulnerable code uses sshpkt_disconnect() in the GSSAPI KEX server path.
 - Upstream OpenSSH/OE-Core does not carry the vulnerable GSSAPI key-exchange delta.
 - Hence ignoring the CVE for this version.
