rs6000: Fix use of wrong enum for built-in function code

I discovered this bug while working on patches to remove the old built-ins
infrastructure.  I missed a spot in converting from the rs6000_builtins enum to
the rs6000_gen_builtins_enum.  This fixes it.  The fix is technically not right
if new_builtins_are_enabled were to be set to zero, but we're not going to do
that anymore, and the remnants of that code will be removed shortly.
