emile/ecore_con: drop SSLv3 support due to security issue.

SSLv3 has been compromised a year ago by what is known as POODLE
(https://en.wikipedia.org/wiki/POODLE). Every major browser have now
dropped support for SSLv3 and distribution are starting to do so also.
It is a good timing for us to do so, especially as it breaks build on
some distribution.
