Log:
  MFC r300376:
  ndis(4): Better mimic the behavior of rand() on Windows.

  In ndis(4) we expose a rand() function that was constantly reseeding
  with a time depending function every time it was called. This
  essentially broke the reasoning behind seeding, and rendered srand()
  a no-op.

  Keep it simple, just use random() and srandom() as it's meant to work.
  It would have been tempting to just go for arc4random() but we
  want to mimic Microsoft, and we don't need crypto-grade randomness
  here.
