Gevent : SSL support fixed for python 2.7.9

Good news for gevent users blocked on python < 2.7.9 due to broken SSL support since python upstream dropped the private API _ssl.sslwrap that eventlet was using.

This issue was starting to get old and problematic since GLSA 2015-0310 but I'm happy to say that almost 6 hours after the gevent-1.0.2 release, it is already available on portage !

We were also affected by this issue at work so I'm glad that the tension between ops and devs this issue was causing will finally be over ;)
