Daniel van Vugt 3f7c1be59a cogl: Remember to bind the GLX context to our drawable before querying
Or else `glXQueryDrawable` will fail per the `GLX_EXT_buffer_age` spec:

> If querying GLX_BACK_BUFFER_AGE_EXT and <draw> is not bound to
> the calling thread's current context a GLXBadDrawable error is
> generated.

This mistake went unnoticed until `mtk_x11_error_trap_push` was introduced
(55e3b2e5193) because for some reason it is incapable of trapping
`glXQueryDrawable`. Prior to that it seems
`cogl_onscreen_glx_get_buffer_age` would trap and so always returned zero.

This means we're reenabling clipped redraws on X11 here for the first
time in a long time.
