Fix CI errors

* Remove deprecated "update-ca-trust force-enable" call
* Create the `/var/run/postgresql` directory. In older versions
of postgresql-server package, this directory was created during
package installation. The newer versions are not creating it
anymore (because systemd was supposed to do it) which is breaking
our s6 based images.
* Change a Containerfile RUN instruction to run dnf once (not a fix,
just a little improvement)
