isohybrid: make isolinux.bin and isohybrid two-way compatible

It turns out we *can* determine if we have the extra partition offset
information after all, by looking at the value of the stack pointer.
This depends on the internals of the old isohdpfx code, but that's
really all we need to worry about.
