meta/classes: fix missing vardeps for CVE status variables

Several CVE helper functions (get_patched_cves() and decode_cve_status())
implicitly depend on the CVE_STATUS and CVE_CHECK_STATUSMAP variables, but
these were not declared in the vardeps of their callers.

On Scarthgap, the upstream fix (2cc43c72ff28aa39a417dd8d57cd7c8741c0e541)
cannot be cherry-picked cleanly, as it also requires BitBake changes.

As a workaround, explicitly add CVE_STATUS and CVE_CHECK_STATUSMAP to the
vardeps of all tasks invoking these helpers, ensuring correct task
re-execution when CVE status changes.

This keeps CVE-related metadata generation consistent without requiring
BitBake modifications.
