ssl: server-side: allow multiple version of TLS 
boost::asio::ssl::context is created using specifically TLSv1.2, which
blocks the ability to use superior version of TLS like TLSv1.3.

Filtering is also made specially later in the code to remove unsafe
version for TLS such SSLv2, SSLv3 etc..

This change is removing double filtering to allow TLSv1.2 and above to
be used.

testssl.sh 3.0rc5 now reports the following (please note monerod was
built with USE_EXTRA_EC_CERT):
