minor issue with /usr/sbin/ms-check

[M A Young]

I am migrating to mailscanner 5 and have noticed that mailscanner can get 
in a state where ms-check will restart it every hour. I am not yet sure 
what causes the initial restart but subsequent restarts are because the 
restarted mailscanner is missing a pid file, which is in turn seems to be 
because the previous mailscanner processes haven't finished when the new 
processes are starting. Adding a short delay to the ms-check script (2 
seconds seems to be enough based on my limited testing) seems to stop the 
repeated restart behaviour.
I have included a possible patch below.
