kris 380cfaba2c For generating ICMP IDs to send, use modulus and addition on a single random ...

number to guarantee it's nonzero (which some target hosts require) rather
than looping for new random numbers.  

* ICMP ID values are unimportant, as long as they are nonzero
* The original code to get random numbers was exactly duplicated (new variable,
  comment, loop, even whitespace) in the same function, so using a single
  variable set initially (albeit differently) simplifies duplication
