check_smtp.c: modified SSL check for use with -e

  - currently STARTTLS check does not work with -e if there's text
    like '220 hostname ESMTP*'. This is caused by SMTP answer from
    host. Postfix answer: 220 2.0.0 Ready to start TLS, Exchange
    2010: 220 2.0.0 SMTP server ready. This fix checks against 220

    closes #1093
