[hostname] T1336: trailing dots in system domain-name are invalid
Debian/Systemd provides hostnamectl which disabllows setting a FQDN when there is a trailing (.) in the provided hostname. Extend regex when setting "system domain-name" that there can't be a trailing (.). Provide migration script for current installations to remove the dot.
