[cogl/wip/rib/master-next: 22/36] tests: ports test-wrap-modes.c to be standalone cogl test

[Robert Bragg <rbragg src gnome org>]

commit 1e20f338d6dff6561605b4313bae244e0fa23400
Author: Robert Bragg <robert linux intel com>

    tests: ports test-wrap-modes.c to be standalone cogl test
    
    This ports test-wrap-modes.c from being a clutter based test to one that
    is a standalone cogl test.
