Import additional bugfix for reading and extracting makefs-created

ISO images with tar.

Vendor revision 3648 (merge of 3647):
Additional fix to issue 168 because the change of r3642 was not sufficient.
  - Make sure "CL" entry appear after its "RE" entry which the "CL" entry
    should be connected with.
  - Give consideration to the case that the top level "RE" entry has
    already been exposed outside before its tree.
