base: Cleanup rpmdb

First, ensure we remove the `-shm` files etc; this is another
implementation of https://github.com/coreos/rpm-ostree/pull/5244
effectively, but in shell script in the container build pipeline.

Also remove the rpm-ostree-base-db because I think it's the
hardlinking here that's causing problems in gitlab CI where
we can't rely on writethrough of hardlinks.

I am hoping this fixes the gitlab CI.
