Fix crash in qt_init when the XFIXES extension is not available.
This happened to me when starting a Qt4 application in VNC
(vncserver, vncviewer -via host, on linux).
The pointers to the xfixes functions were not being set to 0 when
XFIXES is not available, so it would crash later on in the method,
in the (null-checked) use of X11->ptrXFixesSelectSelectionInput.
