Change python_run_simple_file to use gdbpy_ref
This changes python_run_simple_file to use gdbpy_ref and
unique_xmalloc_ptr. Thi fixes a latent bug in this function, where
the error path previously ran the cleanups and then referred to one of
the objects just freed.

* python/python.c (python_run_simple_file): Use
unique_xmalloc_ptr, gdbpy_ref.
