Accept non-localhost connections in ringojs (#2631)

Without this, the client machine running wrk cannot connect to the
server and so ringojs gets zero RPS.

I also removed the & from the end of these lines, which is unnecessary
and potentially problematic for our toolset if/when the server doesn't
launch correctly (the toolset will sit idle for 1 hour and 45 minutes
waiting for the server to appear).
