[cogl/wip/frame-synchronization] Don't convert gettimeofday() UST values

    Don't convert gettimeofday() UST values
    
    Instead of converting gettimeofday() UST values into
    clock_gettime(CLOCK_MONOTONIC, ...), just return them raw, and the
    caller can convert using cogl_clock_get_time().
