[squid-users] squidctl script update

Here's a small update to the squidctl script I submitted soemtime ago,
with a small fix.

Problem :

- when system crashed and a stale PID still existed, squid was not
started with the erroneous assumption that it is still running.

I don't know why, the test
if [ "x$PID" != "x" ] && kill -0 $PID ; then ....
failed to properly detect the stale PID.

FIX :

Changed to a separate if branch and now it works.

Notes :

Script makes a few static assumptions on where the squid binary,
squid.pid and squid.conf files are located.

If your setup differs, please change them.

Also, I look for shutdown_lifetime in squid.conf and add one second to
it to make sure squid makes a clean shutdown. I had some problems at
shutdown if I did not wait at all, also sometimes if I waited just the
amount specified in shutdown_lifetime. After I increased it I had no
problems.
