A few of us helped solve this problem via IRC and I just wanted to share 
the results.

There's an issue where the 'rpm-ostree uninstall' command does not 
support specifying package names for packages that were installed from a 
local RPM.  You need to specify the full NEVRA.

To uninstall the `docker-ce` and `docker-ce-selinux` packages from the 
example above, we needed to run:

# rpm-ostree uninstall docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch 
docker-ce-17.03.2.ce-1.el7.centos.x86_64

This problem spawned the following issue and a PR for documentation 
improvement:

https://github.com/projectatomic/rpm-ostree/issues/1386
https://github.com/projectatomic/rpm-ostree/pull/1388

After the local packages were successfully uninstalled, we were able to 
reset all of the overrides with:

# rpm-ostree override reset --all

The overall issues faced here also started the discussion about 
providing a way to uninstall and reset all the overrides in one command:
