    Don't include cogl/cogl.h from test-utils.h
    
    There was a circular depedency when building from a fresh git clone
    where test-fixtures needs to be built before the cogl directory, but
    test-fixtures also indirectly includes cogl-enum-types.h which is only
    generated when building the cogl directory. If we change the header to
    just include specific cogl headers instead of cogl/cogl.h then we can
    break the circular dependency.
    
    This needs a tweak to test-no-gl-header because that first undefines
    COGL_COMPILATION before including test-utils.h. However it doesn't
    really do any actual work so we can get away without including it.
