  Log:
    random.c: fix need_secure flags
    
    * random.c (fill_random_seed): do not need to be secure, to get
      rid of blocking at the start-up time.
      [ruby-core:87462] [Bug #14837]
    
    * random.c (random_raw_seed): expected to be a cryptographically
      secure, as documented.
