[SPARK-24303][PYTHON] Update cloudpickle to v0.4.4

## What changes were proposed in this pull request?

cloudpickle 0.4.4 is released - https://github.com/cloudpipe/cloudpickle/releases/tag/v0.4.4

There's no invasive change - the main difference is that we are now able to pickle the root logger, which fix is pretty isolated.

## How was this patch tested?

Jenkins tests.
