Export outbound_payment structs in their respective modules

Re-exports in Rust make `use` statements a little shorter, but for
otherwise don't materially change a crate's API. Sadly, the C
bindings generator currently can't figure out re-exports, but it
also exports everything into one global namespace, so it doesn't
matter much anyway.
