py-macholib: updated to 1.9

macholib 1.9

Features:
* Add definition for ``macholib.mach_o.reloc_type_generic``, which
  was used in code but never defined.
* Add LICENSE file
* Added "--help" option for "python -m macholib"
* Added function ``macholib.MachO.lc_str_value`` which should
  help in decoding value of ``macholib.mach_o.lc_str``. Those
  values are offsets in the data of a load command, the function
  will return the actually value as a byte string.

Bug fixes:
* Pull request 15: Fix typo in thread_command class
