Protection name: Supported packages
Check: Ensures that all installed packages are still
marked as supported.
Purpose: Some distributions will mark the packages as supported
either in specific versions, or for a specific period of time.
Unsupported packages will not receive security updates, therefore
they should be validated / replaced if possible.
