    scripts/dl_cleanup: add support for subdirectories
    
    Allow comparing subdirectories exactly like files.
    
    Handle a corner case where the new subdirectory
    has the same tarball inside of it
    as the one that was downloaded
    before a subdirectory for that package was established.
