[clutter] build: make internal option_xkb_* symbols static

[Robert Bragg <rbragg src gnome org>]

    build: make internal option_xkb_* symbols static
    
    This makes the option_xkb_* symbols declared for the evdev device manager
    and the wayland device manager private so we don't get symbol collisions
    if both of these backends are enabled.
