  Issue #11074: Make 'tokenize' so it can be reloaded.

  The module stored away the 'open' object as found in the global namespace
  (which fell through to the built-in namespace) since it defined its own 'open'.
  Problem is that if you reloaded the module it then grabbed the 'open' defined
  in the previous load, leading to code that infinite recursed. Switched to
  simply call builtins.open directly.
