Otherwise all the clients only using control/controlhttp for the ts2021 HTTP client were also pulling in WebSocket libraries, as the server side always needs to speak websockets, but only GOOS=js clients speak it. This doesn't yet totally remove the websocket dependency on Linux because Linux has a envknob opt-in to act like GOOS=js for manual testing and force the use of WebSockets for DERP only (not control). We can put that behind a build tag in a future change to eliminate the dep on all GOOSes.
