no failure code is set if an expiration is detected

[H.-Dirk Schmitt]

usage is:
                ssl-cert-check -x 100 -c cert.pem

I checked it with 3 certificates:

1. valid for a long time (2 years)
2. valid only some days (30 days)
3. already expired

In every 3 cases the utility print out the right diagnosis but doesn't set an error code (<> 0).
So this utility can't be easily used from a shell script.

Problem is in the last lines of the script:

### Exit with a success indicator
if [ "${NAGIOS}" = "TRUE" ]; then
    exit $RETCODE
else
    exit 0
fi

So a workaround is to use the '-n' switch, but this gives a "ugly" message line:

FILE:/.../cert.pem Expired Jan 20 2013 |days=-9
