When building container images in the
https://github.com/freeipa/freeipa-container/ project, we want the individual
steps in the Dockerfile to pass to make sure there aren't any unexpected
errors.

For quite some time, even as early as with Fedora 37, we had

Running scriptlet: freeipa-server-trust-ad-4.10.1-1.fc37.x86_64
338/343
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
warning: %post(freeipa-server-trust-ad-4.10.1-1.fc37.x86_64) scriptlet failed,
exit status 1

Error in POSTIN scriptlet in rpm package freeipa-server-trust-ad

when installing freeipa-server-trust-ad, but the whole rpm transaction passed
and the dnf command returned with exit 0. So we did not care about that failure
because, well, it did not get reported in any way it could be caught.

This has changed with recent registry.fedoraproject.org/fedora:rawhide image
which seem so have rpm-5.99.91-1.fc43.x86_64. Now instead of exiting with 0 as
with previous registry.fedoraproject.org/fedora:rawhide images, the dnf exits
with 1, even if the version freeipa-server-trust-ad-4.12.2-14.fc43.x86_64 is
the same in both cases.

Reproducible: Always

Steps to Reproduce:
1. podman run --rm registry.fedoraproject.org/fedora:rawhide dnf install -y
--setopt=install_weak_deps=False freeipa-server-trust-ad
2. echo $?
Actual Results:

Expected Results:
No error.
