Bump vendored `six` to `1.11.0`bump-vendored-six-to-1.11.0

Bump `six` to `1.11.0`. Most changes do not affect us, but it's good to
stay up to date. Also, we will likely start vendoring `enum34` in which
case https://github.com/benjaminp/six/pull/178 is needed.

Note that this preserves the `kafka-python` customization from https://github.com/dpkp/kafka-python/pull/979
which has been submitted upstream as https://github.com/benjaminp/six/pull/176 but not yet merged.
