Subject: [PATCH] websocket: add missing call to resp.Body.Close

Within hybiClientHandshake, after getting a response from
http.ReadResponse, the body is never closed.

When running a debugger with all of our test cases, this seems to not
matter usually since the body is typically a http.noBody, whose Close
just returns nil. However, this is not always the case. Therefore, this
CL adds the missing resp.Body.Close call.

Fixes golang/go#76952
