Stop relying on the `*Features::known` method in net-tokio

As we move towards specify supported/required feature bits in the
module(s) where they are supported, the global `known` feature set
constructors no longer make sense.

Here we stop relying on the `known` method in the
`lightning-net-tokio` crate.
