[OE-core][wrynose][PATCH v2] openssh: set status for CVE-2026-59998

["Devansh Patel -X (devanshp - E INFOCHIPS PRIVATE LIMITED at Cisco)" <devanshp@cisco.com>]

From: Devansh Patel <devanshp@cisco.com>

Analysis:
- CVE-2026-59998 concerns an undocumented limitation of
  GSSAPIStrictAcceptorCheck in Windows Active Directory environments [1].
- Upstream OpenSSH 10.4 only documents the existing behavior and provides no
  code remediation [2].
- The recipe disables Kerberos/GSSAPI by default. Mark the CVE
  not-applicable-config when PACKAGECONFIG lacks kerberos, and unpatched when
  kerberos is enabled.

Changes in v2:
- Drop the documentation-only backport for CVE-2026-59998.
- Add a configuration-aware CVE_STATUS that reports unpatched when Kerberos
  support is enabled and not-applicable-config otherwise.
