cve-check: encode affected product/vendor in CVE_STATUS

CVE_STATUS contains assesment of a given CVE, but until now it didn't have
include the affected vendor/product. In the case of a global system include,
that CVE_STATUS was visible in all recipes.

This patch allows encoding of affected product/vendor to each CVE_STATUS
assessment, also for groups. We can then filter them later and use only
CVEs that correspond to the recipe.

This is going to be used in meta/conf/distro/include/cve-extra-exclusions.inc
and similar places.
