[TRIVIAL] [2.{4,5} TRIVIAL PATCH] Change list_emtpy() to take a const pointer

[Rusty Trivial Russell]

  Hi Rusty, list
  
  Didn't know what was the best place to submit this one, I
  guessed trivial.
  
  Just change the definition of list_empty() to take a const
  pointer. I have some upper layers of code that do all the
  const/non-const thing and list_empty() breaks it without
  this.
