dwarflint: Add an ability to list registered checks

- because the check descriptor is quite simple as of now, the usefulness
  of this is rather limited
- plus unregistered checks are not listed, which means that the user will
  never know about prereqs like .debug_info.  Hard to say whether this is
  a problem or not
