Bring carbon upstart recipes into line for ea27d1a

ea27d1a broke upstart support, since upstart was omitted from that PR.  This brings upstart into line with the new code.  I'm not sure I really see the point in removing init script duplication, only to introduce recipe duplication, but that's an aside, and maybe I'm missing the point there.  Anyway, this makes upstart work again, which is what my env needed.
