[mutter/wayland] Add an option to run as a wayland compositor

[Giovanni Campagna <gcampagna src gnome org>]

commit 4494888b8227687d0492a74df1a8acb708003011
Author: Giovanni Campagna <gcampagn redhat com>
Date:   Wed Sep 11 10:22:58 2013 +0200

    Add an option to run as a wayland compositor
    
    Move the option from the mutter binary to libmutter, and
    rename from --nested to --wayland.
    This allows gnome-shell to drop the set_is_wayland_compositor()
    call.
