Don't silently ignore failures in RPM test step in CI

Because the RPM test is a separate step, it requires other modules build
in this job to be installed in the local repo, to avoid building most
modules twice. This in turn requires to manually clean them later
to avoid caching them in Github, because only dependencies should be
cached.
