generate_bom: Move whitelist logic to check_bom

In some cases it is necessary to whitelist the license report generated in the BOM file, until a proper fix is found. Currently this is done through a list a of whitelist packages that are checked during BOM file build. Unfortunately the current approach overrides the license with Whitelisted loosing important information.

In order to avoid loosing license information move the whitelist logic to check_bom and keep the license information intact.

Additionally, fix the behavior of check_bom when used with high verbose level, to display license issues in packages and binaries.
