The services and timers are not useful if a repo is not configured.
In OE, we default to have no repo configured. So we default to disable
these units.
The problem was found by the test_systemd_failed runtime test case.
dnf-makecache.service is found to fail. This is due to lack of repo.
Note that as this service is started by the dnf-makecache.timer, it's
possible that test_systemd_failed passes in case the timer is not started
yet.
