    fetch2: Skip lockfiles and donestamps for local files
    
    For local files, there are no races with downloads, we don't need ".done"
    stamps and we don't need lockfiles.
    
    This considerably cleans up DL_DIR and all the pointless ".done" files
    as well as removes stalls over local files with the same name.
