Update graphics/py-Pillow to 3.2.0

pkgsrc changes:
o Simplify MASTER_SITES
o Add LICENSE
o Disable the tests for now (that were also broken for 3.1.2 version).
  All the modules are builded in build/lib.*/PIL/ while selftest.py just
  checks in PIL/. Manually cp(1)-ing all the build/lib.*/PIL/ files in PIL/
  work as a workaround (and all test are passed) although implementing a
  similar (distutils.cmd) logic will be easily buggy.
