rs6000: Fix fake vec_promote overload

rs6000-overload.def defines one instance of vec_promote so that it can be
registered with the front end.  Actual expansion of the vec_promote overload
is done with special-case code in rs6000-c.c.  During another cleanup, I
observed that the fake instance has the wrong number of arguments.  Fix that.
