[OE-core] [scarthgap] [PATCH 1/7] curl: ignore CVE-2026-4873

["Anil Dongare -X (adongare - E INFOCHIPS PRIVATE LIMITED at Cisco)" <adongare@cisco.com>]

From: Anil Dongare <adongare@cisco.com>

- CVE-2026-4873 affects curl before 8.20.0 when a connection negotiated with
  clear-text IMAP, POP3, or SMTP can later be reused for a TLS-required
  transfer.
- In scarthgap, these protocols are optional PACKAGECONFIG entries and are not
  enabled by default in `curl_8.7.1.bb`.
- Record this CVE as configuration-not-applicable for the default recipe
  configuration instead of carrying the upstream fix unconditionally.

Reference:
- https://curl.se/docs/CVE-2026-4873.html
- https://nvd.nist.gov/vuln/detail/CVE-2026-4873
