Set PYTHON_PY3K_PLIST_HACK to adjust the plist for Python >= 3.2.0.

Since this port does not use distutils/setuptools and we manually generate
the .pyc/.pyo files, we need to set PYTHON_PY3K_PLIST_HACK so that the cache
files end up in the right directory if Python >= 3.2.0 is used due to
PEP-3147.
