pylint: upgrade to 1.3.1

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.

We include the six module since not all bots have it, and it's small.

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

Was it required? It feels like a regression. For example in
http://build.chromium.org/p/tryserver.chromium.linux/builders/chromium_presub...

it's not possible to know the error ID so it can be silenced locally, making
silencing spurious errors tedious.

removing it was on purpose because pylint warns:
Warning: option include-ids is deprecated and ignored.

as for your issue, the thing to use is at the end of the message:
R:  1, 0: Cyclic import (telemetry.core.platform ->
telemetry.core.platform.linux_platform_backend ->
telemetry.util.support_binaries -> telemetry.util.cloud_storage) (cyclic-import)

use "cyclic-import" instead of "R###" now.
