spdx: extend CVE_STATUS variables

spdx: extend CVE_STATUS variables

If spdx is generated without inheriting cve/vex classes (which is poky
default), only explicitly set CVE_STATUS fields are handled.
Calculated ones (e.g. from CVE_STATUS_GROUPS) are ignored.

Fix this by expanding the CVE_STATUS in spdx classes.
