            skip the real scenario if the service is missing

The systemd-timesyncd service is present on both RHEL-8 and Fedora,
but may not be present on other RHELs, even though the policy which
confines the systemd-timesyncd program is present there.
If the systemd-timesyncd service is not present then the TC checks
policy definitions only (types, rules, file context patterns etc.)
If the systemd-timesyncd service is present then the TC will also
test basic actions of the service (start, restart, status etc.)
