vendored Docker SDK for Python code: fix: eventlet compatibility

Check if poll attribute exists on select module instead of win32 platform check

The implementation done in #2865 is breaking usage of docker-py library within eventlet.
As per the Python `select.poll` documentation (https://docs.python.org/3/library/select.html#select.poll) and eventlet select removal advice (eventlet/eventlet#608 (comment)), it is preferable to use an implementation based on the availability of the `poll()` method that trying to check if the platform is `win32`.

Fixes docker/docker-py#3131
