Stop creating /var/lock/subsys and polluting it with a MailScanner lockfile
that no-one's using.

Do not consider a missing PID file a reason for restarting the daemon. Most
likely it's just been installed and never been started or stopped (so
MailScanner.off doesn't exist).

Drop the check whether MailScanner is configured. Our start script is not using
it (if it's enabled, it's enabled) and ms-check will still only do anything if
the pidfile exists but no process named MailScanner with that pid exists and
the stopped_lockfile doesn't exist. This should be safe enough.
