cve-check.bbclass: do not download the CVE DB in package-specific tasks

Disable downloading of the vulnerability DB in do_check_cves() task.

When invoked in this task, cve-check-tool attempts re-download of the CVE DB
if the latter is older than certain threshold. While reasonable for a
stand-alone CVE checker, this behavior can cause errors in parallel builds
if the build time is longer than this threshold:
* Other tasks might be using the DB.
* Several packages can start the download of the same file at the same time.

This check is not really needed, as the DB has been downloaded by
cve_check_tool:do_populate_cve_db() which is a prerequisite of any do_build().
The DB will be at most (threshold + build_time) old.
