Drop unused type parameter on BlindedRoute::new

Browse source 
I'm not sure why rustc didn't complain about the unused parameter
or why we're allowed to get away without explicitly bounding the
`Sign` in the `KeysInterface`, but the current code requires all
`BlindedPath` construction to explicitly turbofish an unused type.
