py/objgenerator: Implement __name__ with normal fun attr accessor code.

With the recent change b488a4a8480533a6a3c9468c2f8bd359c94d4d02, a
generating function now has the same layout in memory as a normal bytecode
function, and so can reuse the latter's attribute accessor code to
implement __name__.
