parsers: avoid PySliceObject cast on Python 3
PySlice_GetIndicesEx() accepts a PySliceObject* on Python 2 and a
PyObject* on Python 3. Casting to PySliceObject* on Python 3 was
yielding a compiler warning. So stop doing that.
With this patch, I no longer see any compiler warnings when
building the core extensions for Python 3!
