sphinx: Updating daemon to new sphinx implementation 

Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.

It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
