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

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

From: Devansh Patel <devanshp@cisco.com>

The default product-only mapping generates a vendor-wildcard CPE.
perl:perl is the active NVD dictionary CPE and configuration identity and
also covers CNA affected data using vendor perl. larry_wall:perl preserves
historical NVD configurations.

leont:perl covers authoritative CNA affected data for the same Perl/perl5
source, including CVE-2026-15534. It has no dictionary record.

This changes the generated identities to three exact CPEs, but the frozen
sbom-cve-check database leaves the 61-entry CVE report unchanged, with no
current CVE delta.
