Subject: [PATCH] Automatic file `/etc/opendkim/TrustedHosts` creation if
 missing

Following issue #132, the script `start-mailserver.sh` now creates and populates `/etc/opendkim/TrustedHosts` with localhost information.
This allow for mounting an empty directory from the host for DKIM data persistence.
