fusee_cpp: implement package2 rebuild/kip patching

fusee_cpp: fix mariko mtc (mariko now gets as far as erista)

fusee_cpp: validate mtc overlay before jumping to it. ...

mtc will jump back to us, so we need a compatible binary.

This also makes some changes to our layout to minimize the likelihood of
an incompatible mtc binary (I made some arbitrary .text/.rodata/.rwdata changes)
and saw identical mtc binaries, so hopefully this all works out.
