MAR-27: Update mail_forwarder role/tests:
- Install swaks on mail-server instance for testing SMTP.
- Install procmail via mail_forwarder role (needed to be explicit for Debian
Stretch).
- Introduce small sleep when mails are sent to localhost for delivery to remote
hosts before checking the logs in order to allow Postfix to process the
queue.
