ui/gtk: Make sure the right EGL context is currently bound
Observed a wrong context is bound when changing the scanout mode.
To prevent problem, it is needed to make sure to bind the right
context in gtk_egl_set_scanout_mode/gtk_gl_area_set_scanout_mode
as well as unbind one in the end of gd_egl_update/gd_gl_area_update.
