Add a flag to remove producers section

Browse Source 
This should help handle instances like the recent Webpack bug and is
also a useful flag in its own right. For now it's set to `false`, but if
the Webpack bug persists through to tomorrow we likely want to publish a
version of `wasm-bindgen` with it default set to `true`.
