xcb: Properly interpret data.l[0] field of XdndStatus message 

The standard https://freedesktop.org/wiki/Specifications/XDND/
states: "In order for the proxy window to behave correctly, the
appropriate field of the client messages, window or data.l[0],
must contain the ID of the window in which the mouse is located,
not the proxy window that is receiving the messages."

So compare it with the current target window instead of the
current proxy window.
