    build: make wayland support unconditional
    
    In the wayland branch of mutter, we want to build a wayland version
    of the mutter libraries, and that's much easier if we just build
    wayland support unconditionally.
    The define is kept to avoid a huge diff, but should be removed
    in a later patch.
    Also, wayland support can still be disable at runtime, by
    launching mutter without the --nested switch.
