xcb: Set WM_CLIENT_MACHINE property
It can be useful to detect that a window belongs to an application running on a remote host. E.g. a window manager may display the name of the remote host in the window title. Or it can detect whether a client can be killed. This property is set by Xlib's function XSetWMProperties(), which is called by GTK and Qt 4, so it's also good to do for consistency.
