This updates all scripts in the Djblets tree to use python3 instead of
python, ensuring that the right version is used when in an environment
containing both versions.

run-pyflakes.py needed some changes to run on Python 3. While we may
want to remove this script, that's a decision that'll be left for after
this update.

Tested all scripts and made sure they ran.
