Import ChannelTransactionParameters from its real path

Rather than importing `ChannelTransactionParameters` via the `use`
in `lightning::sign`, import it via its real path in
`lightning::sign::ecdsa`. This makes reading the code (incredibly
marginally) simpler, but also makes the bindings generator happy.
