go/doc: set receiver type position for embedded methods

Browse Source 
This was a bug that didn't manifest itself before CL 7674044;
but with that CL and without this fix, the go/doc tests fail.
(The bug fixed by 7674044 and the bug fixed here cancelled
each other out w/ respect to the go/doc tests).
