[issue29914] Incorrect signatures of object.__reduce__() and object.__reduce_ex__()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

The special method __reduce__() doesn't take arguments, the special method __reduce_ex__() takes one mandatory argument. But default implementations in the object class takes one optional argument. This looks as an oversign. Proposed patch fixes signatures of object.__reduce__() and object.__reduce_ex__().
