python.el: Fix close paren indentation to match pep8 (Bug#20742)

* lisp/progmodes/python.el (python-indent--calculate-indentation):
When opening paren is followed by newline the closing paren should
follow the current indentation.  Otherwise the closing paren should be
aligned with the opening paren.  This fixes the latter case.
