Install chrome for browser testing
The unzip util is not part of the recipe standard library (called
"recipe_engine"), so I copied it from chromium's util folder (called
"recipe_modules") to our util folder.
The env stuff is done a bit differently than the original code from
gerrit_plugins.py because we are not running karma. Possibly this will
take some adjusting, but according to
https://github.com/GoogleChrome/chrome-launcher#launch-options it should
detect chrome on the PATH without needing to set CHROME_PATH ourselves.
