Issue #9869: Make long() and PyNumber_Long return something of type
long for a class whose __long__ method returns a plain int. This
fixes an interpreter crash (due to long_subtype_new assuming
PyNumber_Long returns a long) when initializing an instance of a long
subclass from an object whose __long__ method returns a plain int.
