glx: Don't destroy DRI2 drawables for legacy glx drawables

For GLX 1.3 drawables, we can destroy the DRI2 drawable when the GLX
drawable is destroyed.  However, for legacy drawables, there os no
good way of knowing when the application is done with it, so we just
let the DRI2 drawable linger on the server.  The server will destroy
the DRI2 drawable when it destroys the X drawable or the client exits
anyway.
