bpo-43413: Fix handling keyword arguments in subclasses of some buitin classes (GH-26456)

Browse source 
* Constructors of subclasses of some buitin classes (e.g. tuple, list,
  frozenset) no longer accept arbitrary keyword arguments.
* Subclass of set can now define a __new__() method with additional
  keyword parameters without overriding also __init__().
