Autotest for browser_tests does not work on ChromeOS without this change. Python
complains about these modules being deprecated.

I've checked this lib upstream before I made this change - there were no new
updates of any sort there.

Did you mean "from hashlib import md5, sha1"
md5 seems to be used below in this and other files
