Improve banner (3.2)

Browse Source 
... for readability and bugs to be filed (fixes #2506)

This PR defines a short string for the OpenSSL banner as some suppliers have made them (unnecessarily) long so that it won't fit nice in the banner anymore.

The banner also now omits the built line from openssl as for the user it is normally not important.
