Update Monocypher yet again, to 4.0.1

There's a solid chance this actually gets used this time. Plus, there's
breaking changes, so it makes sense to update before writing any actual
code for it.

The RNG module is also manually fixed up; upstream wasn't moved to the
new Monocypher APIs which might be because the authors don't seem to
think it's even a good idea to use anything other than arc4random().
Maybe I'd kind of agree with that if not for both Linux and Windows not
having arc4random(), and none of SSTs use cases requiring it either
(none of the crypto code is gonna be multithreaded and certainly none of
it is gonna fork).
