pylint: upgrade to 1.3.1

The current pylint is very old at this point.  Pull in the latest version
as it supports a lot more features.  Also need to fix the pylint wrapper
to actually update sys.path to use the local modules.

This will trigger new warnings in files, but they look like legitimate
issues that should be fixed at some point.

Revert "pylint: upgrade to 1.3.1"

This reverts commit 451939d582195f20d721bee5ee4d4f4b929c728d.

Throws an exception with a missing import, breaking Telemetry's
presubmit checks and presumably presubmit checks for all Python files
in Chromium. See comment on https://codereview.chromium.org/707353002/ .
