daemon/sphinx: support modern v0 hop payload.
...
This just means we put the outgoing_cltv_value where we used to put zeroes.
The old daemon simply ignores this, but the new one should check it as per
BOLT 4.

sphinx: Removing last vestiges of the end-to-end payload

don't have any plans of re-adding it for the moment, so let's get rid
of the unused code.

...
If I'd known how large this patch would be (though trivial), I'd
have done it in parts.
