Emmanuele Bassi 9090070a98 x11: Refresh key mapping when notified by X11
Use both the MappingNotify event and the XKB XkbMapNotify event, if
we're compiled with XKB support.

This change is also useful for making ClutterKeymapX11 an event
translator and let it deal with XKB events internally like we do for
stage and input events.

Based on a patch by: Damien Lespiau <damien.lespiau@intel.com>
