build: avoid python 2.4 build failure
build: avoid python 2.4 build failure

I'm not sure when Py_ssize_t was introduced; but Fedora 14 Python 2.7
has it, while RHEL 5 Python 2.4 lacks it.  It should be easy enough
to adjust if someone runs into problems.

* python/typewrappers.h (Py_ssize_t): Define for older python.
