Subject: [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.
