glx/present: Only send GLX_BufferSwapComplete for PresentCompleteKindPixmap 

Present didn't provide the 'kind' argument to the
present_complete_notify hook that GLX uses to construct
GLX_BufferSwapComplete events, so GLX was reporting events for
PresentCompleteKindMSC notifications, which resulted in duplicate
GLX_BufferSwapComplete events and crashes in clutter.

See the gnome bug: https://bugzilla.gnome.org/show_bug.cgi?id=733282
