rust-cpython: add wrapper around decapsule_make_dirstate_tuple()

There are a couple of safety issues. First, the returned function pointer
must be unsafe. Second, its return value must be a raw pointer (i.e.
python27_sys::PyObject), not a cpython::PyObject. The wrapper function will
address these issues.
