The `@core` package group used to include TuneD package by default on
RHEL-8. It has been removed from the group in Fedora as part of [1] and
inherited into RHEL-9. As a result, TuneD is no longer installed by
default on RHEL images.
After a discussion on rhel-devel there seems to be an agreement, that
TuneD should be installed by default on all RHEL virtual images. At
least we should keep the consistency in this regard with RHEL-8.
Regenerate all RHEL-9.0 image test cases.
