    lib/bb/checksum: avoid exception on broken symlinks
    
    If using OE's externalsrc with a source tree that is not tracked by git
    and contains broken symlinks, you can receive "TypeError: unorderable
    types: NoneType() < str()" within the file checksum code due to:
    
     checksums.sort(key=operator.itemgetter(1))
    
    Don't add files with no checksum to the checksums list in order to avoid
    this.
