fix Python deprecation warnings about PY_SSIZE_T_CLEAN

Browse Source 
Summary:
Update pywatchman/bser.c to define `PY_SSIZE_T_CLEAN` before including
`Python.h` and then receive parsed string lenghts as `Py_ssize_t` rather than
`int`.  This eliminates some runtime Python warnings about the old `int`
behavior being deprecated.
