[issue26634] recursive_repr forgets to override __qualname__ of wrapper

[Xiang Zhang]

New submission from Xiang Zhang:

In reprlib.recursive_repr, it seems __qualname__ is forgotten. Giving the example in reprlib document, it gives a strange result 'recursive_repr.<locals>.decorating_function.<locals>.wrapper' of Mylist.__repr__.__qualname__.

I simply add the assignment of __qualname__. But I doubt the treatment of __module__, __doc__, __name__, __qualname__ will raise AttributeError when they don't exist in user_function. Is this the desired behaviour or we'd better treat them like functools.update_wrapper, catch and then ignore the error.
