io/channel-websock: treat 'binary' and no sub-protocol as the same

noVNC doesn't use 'binary' protocol by default after
commit c912230309806aacbae4295faf7ad6406da97617.

It will cause qemu return 400 when handshaking.

To overcome this problem and remain compatibility of
older noVNC client.

We treat 'binary' and no sub-protocol as the same
so that we can support different version of noVNC
client.

Tested on noVNC before c912230 and after c912230.
