chrony.conf moved content_rule_chronyd_specify_remote_server now broken

#### Description of problem:
It seames like `chrony.conf` has moved from `/etc/chrony.conf` to `/etc/chrony/chrony.conf`.
This means `xccdf_org.ssgproject.content_rule_chronyd_specify_remote_server` will consistently fail as it only checks in `/etc/chrony.conf`. Other rules might also be affected!
