test-tls-no-sslv3 and shared openssl with disabled SSLv3

[kapouer]

Hi,

debian/sid is transitioning
to an openssl version built with disabled SSLv3 support.
It is disabled to the point that
openssl s_client -connect example.com:443 -ssl3
fails immediately with unknown option -ssl3 error message.

The test actually fails when checking that the server emits a clientError:
because the client fails immediately, no failure happens on the server.

I can easily fix the test on debian but am not sure if it should be fixed here
as well. What do you think ?
