[clutter] build: Allow disabling all tests and examples

[Emmanuele Bassi <ebassi src gnome org>]

    build: Allow disabling all tests and examples
    
    This should allow nicer build automation and cross-compilation support.
    
    The former --disable-conformance configure switch has been deprecated by
    the --disable-tests one, which is more encompassing as it disables the
    whole test suite.
