spdx30: fix cve status for patch files in VEX

This commit fixes commit 08595b39b46ef2bf3a928d4528292ee31a990c98
which adapts vex creation between function create_spdx where all changes
were backported and funtion get_patched_cves where changes were not
backported.

CVE patches were previously ignored as they cannot be decoded from
CVE_STATUS variables and each caused a warning like:
WARNING: ncurses-native-6.4-r0 do_create_spdx: Skipping CVE-2023-50495 — missing or unknown CVE status

Master branch uses fix-file-included for CVE patches however since
cve-check-map.conf was not part of spdx-3.0 backport, closest one
available (backported-patch) was implemented.
