Some CVEs may be patched during the build process without incrementing
the version number, save the CVEs fixed by patches to cve_by_status
which was parsed as "Patched" status to add new_vex_patched_relationship
to pkg_objset
Take recipe unzip for example, CVE-2015-1315 is patched in oe-core and
is available in package SPDX
oe-core$ grep "CVE-2015-1315" -rn meta
