[Buildroot] [PATCH v5 2/3] support/script/cve-checker: Manage the CVEs that need to be check

[Gregory CLEMENT <gregory.clement@bootlin.com>]

When looking for if a package is affected, the version comparison can
fail. This means that we don't know if the version of the package used
is affected or not and we need to check manually the version.

This patch exposes this new information in json and html format.
