Tests: unbreak ssl_session_ticket_key.t with old IO::Socket::SSL.

Once ssl_session_ticket_key.t was rewritten using IO::Socket::SSL,
it requires SSL_session_key and TLSv1.3 session reuse support checks.
Although SSL_session_key has been introduced in IO::Socket::SSL 1.965,
further improvements appeared in 2.030 are needed for tests to work.
