[OE-core][PATCH] expat: correct CVE_PRODUCT mapping

[OE-core][PATCH] expat: correct CVE_PRODUCT mapping

[Devansh Patel -X (devanshp - E INFOCHIPS PRIVATE LIMITED at Cisco)]

From: Devansh Patel <devanshp@cisco.com>

The current product-only mapping generates vendor-wildcard CPEs, while
the old libexpat:expat dictionary entries are deprecated.
libexpat_project:libexpat is the active NVD dictionary CPE and
configuration identity, and is also used by CNA affected-data records
for the packaged libexpat source.

This changes the generated product identity. With the frozen
sbom-cve-check database, the 63-entry CVE report is unchanged, so this is
an identity correction with no CVE delta.

Hi,

This change would exclude CVEs that actually do apply to expat, such as
CVE-2026-76641 which has CPE libexpat:libexpat in the MITRE database
(most easily seen in the json representation [1]). I don't think it is
correct.

What was the motivation to change this CVE_PRODUCT assignment?
