[issue32034] Error when unpickling IncompleteReadError

There is the same issue with LimitOverrunError.

I'm not sure that we should keep args the same. It affects __str__ and __repr__. badouxn overrides __str__. And the result of __repr__ currently looks like the exception constructor, but actually is not compatible with it.

>>> IncompleteReadError(b'abc', 10)
IncompleteReadError('3 bytes read on a total of 10 expected bytes',)
