ui/gtk: Draw guest frame at refresh cycle 

Draw routine needs to be manually invoked in the next refresh
if there is a scanout blob from the guest. This is to prevent
a situation where there is a scheduled draw event but it won't
happen bacause the window is currently in inactive state
(minimized or tabified). If draw is not done for a long time,
gl_block timeout and/or fence timeout (on the guest) will happen
eventually.

v2: Use gd_gl_area_draw(vc) in gtk-gl-area.c
