[PATCH] ui/vnc.c: Allow websocket connections over AF_UNIX sockets

[Pierre-Yves Ritschard <pyr@spootnik.org>]

Hi,

The provided patch allows the VNC websocket server of a qemu process to
be provided over AF_UNIX as it is already possible for standard TCP VNC
servers.

Now that many clients support websocket connections, some exclusively,
it can be useful to expose the VNC server. One such case is when a
proxy is present on a host machine, allowing it to proxy to a
deterministic location withouth having to keep track of port mappings.

Removing the condition as is done in the provided patch creates a 
functional server. If there's a downside to this approach I could not
figure it out while reading the code. My hunch was that the condition
was there for a reason, but it did not jump at me.

Cheers,
  - pyr
