Subject: Only move /var/run/motd.new if it exists.

Only move /var/run/motd.new if it exists.

We must be hitting a race condition when update-motd is installed, since
we've only just written to /var/run/motd.new when we try and write to it.

From Launchpad:
Cron script spams due to not suppressing error when there is no /var/run/motd.new
