Joey Parrish ac125564b9 build: Fix pylint 2.10 issues, use python3 where possible 
The newest pylint release complained about several issues that the
older release did not.  This resolves those issues:

 - removes unneeded "u" prefix from strings
 - adds "encoding" parameter for all open() calls
 - because "encoding" is a python3-only parameter, use python3 in all
   the scripts that we control

Unfortunately, python2 is required for any scripts that import modules
from the ancient Chromium build system we're using (referenced by
DEPS), as well as kokoro scripts.
