tools: Use Python 3 style print statements [9/9]

Initial conversion performed using '2to3 -f print .'.
Imports added and duplicate parentheses removed manually.
Manually converted files, comments and inline code that 2to3 missed.
Afterwards ran "git cl format --python" and cherry-picked the formatting changes.

There are no intended behavioural changes.
