BUG/MINOR: ssl: remove haproxy SSLv3 support when ssl lib have no SSLv3

The commit 5db33cbd "MEDIUM: ssl: ssl_methods implementation is reworked and
factored for min/max tlsxx" drop the case when ssl lib have removed SSLv3.
The commit 1e59fcc5 "BUG/MINOR: ssl: Be sure that SSLv3 connection methods
exist for openssl < 1.1.0" fix build but it's false because haproxy think
that ssl lib support SSLv3.

SSL_OP_NO_* are flags to set in ssl_options and is the way haproxy do the
link between ssl capabilities and haproxy configuration. (The mapping table
is done via methodVersions). SSL_OP_NO_* is set to 0 when ssl lib doesn't
support a new TLS version. Older version (like SSLv3) can be removed at
build or unsupported (like libressl). In all case OPENSSL_NO_SSL3 is define.

To keep the same logic, this patch alter SSL_OP_NO_SSLv3 to 0 when SSLv3 is
not supported by ssl lib (when OPENSSL_NO_SSL3 is define).
