CHROMIUM: config: Make kernelconfig script python3 happy

Because python3 is 50% better than python2.

Specifically note:

* You can't just index the result of a dictionary's "values()"
  function in python3.  I guess it was assumed that everyone who was
  doing that was probably doing something wrong.  In this case the
  script actually wasn't.  It just needed any arbitrary value to seed
  its iteration.  ...but we can write the code differently.
* Print changed.
