[REF] packaging: redhat: use fedora for testing

Creating a centos docker image fails on our nightly server with
this issue: https://github.com/docker/hub-feedback/issues/461

To create a centos image, we used another repository to host the
image and we make it build in docker hub, then we pulled it. It
was getting really annoying.
