depot_tools ships a "vpython" binary that is added to the $PATH for all Chromium engineers. This binary is versioned by depot_tools which we roll in ourselves as part of `gclient sync`. By using `vpython` instead of `python`, we are no longer depended on the Python version installed locally and instead use the version we pull in from DEPS.
