Upgrade Wheel to 0.38.1 on Docker

[Gpetrak]

Wheel is not installed on local GeoNode installation. However, Docker installs wheel with version 0.37.1 by default through this Dockerfile: https://github.com/GeoNode/geonode/blob/master/scripts/docker/base/ubuntu/Dockerfile without defining it explicitly.

Thus, since we have to upgrade wheel to 0.38.1, we have to explicitly define the version of the wheel on the Dockerfile.
