[x11] Unset the GL context when re-realizing

Setting the stage window using the set_stage_foreign() method will
lead to a re-realization. We need to make sure that the Drawable
currently associated to the GL context is set to None, to avoid a
BadDrawable error or, if we're unlucky, a segfault in the X server.
