Amend fix for CVE-2014-3566: only disable SSLv3

It turns out that many clients encapsulate their TLS handshake inside a
protocol called SSLv2Hello. If we disable all protocols containing the string
"SSL", we also disable support for this handshake, which in particular breaks
some python clients running on RHEL5.

The SSLv2Hello protocol itself has no known issues, so we can safely just
disable SSLv3.
Update version to 6.1.26.cloudera.4
