Fix recursion query in find_unblocked_orphans.py
    
    There is a check in find_dependent_packages() to prevent packages reported as
    depended upon when the dependency can be resolved by another package.
    
    For some reason, for (some?) Python packages, this check triggered even for
    packages from the same component. This usually stopped the dependency query on
    the first level even if many other packages depended recursively.
    
    This fixes the problem by explicitly not triggering the check for packages
    from the same component.
