[PATCH 2/2] test/test-lib.sh: launch smtp-dummy with --background and finally kill(1) it.

[Tomi Ollila]

Take the new --background option of smtp-dummy to use so that it is known
there is smtpd listener ready when it is needed. As the smtp-dummy instance
is no longer child process of the script sending SIGKILL to it is the only
way to make sure the instance exits when required.
