    scripts/package-metadata.pl: remove broken detection of self-dependencies
    
    A self-dependency is not an error worth a warning; rather, it is very
    common: whenever there are dependencies between different binary packages
    originating from the same source package, such dependencies occur. Not
    actually generating dependency rules is correct, but already handled a few
    lines below.
    
    A typo prevented this redundant rule from working, which is the reason the
    warning was not actually printed.
