[clutter-gtk/multi-backend] Clean up the build system

[Emmanuele Bassi <ebassi src gnome org>]

commit 3883c54b195df571e84ff2f5b694480cc17af151
Author: Emmanuele Bassi <ebassi linux intel com>
Date:   Fri Sep 30 15:45:50 2011 +0100

    Clean up the build system
    
    We don't need flavours any more, given that Clutter and GTK can be
    compiled with multiple backend in the same shared library, and that
    we need to check at both compile and run-time that the correct backends
    are available.
