[commit] remove useless call to gdbpy_print_stack

[Doug Evans]

Hi.

I've committed this.
PyRun_SimpleFile will print a traceback itself, and clear the
error indicator, so calling gdbpy_print_stack is pointless.
Mea Culpa.

	* python.c (source_python_script): Add comment.
	(source_python_script_for_objfile): Remove unnecessary call to
	gdbpy_print_stack.
