[GLX] Don't request exposure events for child windows

After [1], Chrome and ANGLE use separate X11 connections, so in order for Chrome to receive exposure events, it must select for them its own connection, which is done in [2]. The events selected by ANGLE's connection are never dispatched, so they queue up indefinitely and leak until the connection is closed (when happens when Chrome closes). This change removes the request to receive exposure events.
