hw/xwin: Don't assume we'll always have converted the clipboard selection after 2 attempts 

Rather than knowing we have to call winProcessXEventsTimeout() for up to 2 WIN_XEVENTS_CONVERT messages, process
all messages in winProcessXEventsTimeout() until either: (i) the time out expired, (ii) an error occurred, or
(iii) received a WIN_XEVENTS_NOTIFY messaage indicating the data has been to put on the clipboard.
