bitbake: asyncrpc: serv: correct closed client socket detection

Browse Source 
If the client socket is closed, asyncio.StreamReader.readline() will
return an empty bytes object, not None.

This prevents multiple tracebacks being logged by bitbake-hashserv each
time bitbake is started and performs a connection check.
