Add missing wolfSSL includes and alert history logging.

Without the relevant settings header included, nginx's test program compilation will fail:

Added alert history logging. Example:

2022/07/01 12:08:01 [crit] 74236#0: *1 SSL_do_handshake() failed (RX alert: level=fatal,code=illegal_parameter, TX alert: level=none,code=none) while SSL handshaking, client: 127.0.0.1, server: 0.0.0.0:1443
2022/07/01 12:08:01 [crit] 74236#0: *1 SSL_do_handshake() failed (SSL: received alert fatal error unknown error number) while SSL handshaking, client: 127.0.0.1, server: 0.0.0.0:1443

Unfortunately it isn't feasible to add it to the existing line with how nginx's logging is set up.
