shared/cpu-set-util: only force range printing one time
    
    The idea is to have at least one range to make the new format clearly
    distinguishable from the old. But it is enough to just do it once.
    In particular, in case the affinity would be specified like 0, 2, 4, 6…,
    this gives much shorter output.
