Subject: [PATCH] Define PY_SSIZE_T_CLEAN

When PyArg_ParseTupleAndKeywords() is used with format argument "s#"
that means get a string and his length then the length is returned as
as a Py_ssize_t in python3 but as an int in python2, which casues
a problem because rpmfd_write() that uses PyArg_ParseTupleAndKeywords()
expects the length as a Py_ssize_t always. This problem affects big
endian systems with python2 as default. If PY_SSIZE_T_CLEAN is defined
then PyArg_ParseTupleAndKeywords() returns the length as a Py_ssize_t
in both python2 and python3.
