set colorama upper bound to <0.4.4
colorama v0.4.4 (released in the last 24 hours) is missing an sdist, which trips up the homebrew packaging step of our [dbt release flow](https://github.com/fishtown-analytics/dbt-release/runs/1249693542). Let's set the [upper bound](https://github.com/fishtown-analytics/dbt/blob/dev/kiyoshi-kuromiya/core/setup.py#L67) to <0.4.4 instead of <0.5 for now.
