wolfssl: adjust to new API in v4.2.0

WolfSSL has recently added many openssl 1.1+ calls, including
TLS_server_method & TLS_client_method, which were being redefined,
causing compilation failure:
ustream-openssl.c:113:0: error: "TLS_server_method" redefined [-Werror]
ustream-openssl.c:114:0: error: "TLS_client_method" redefined [-Werror]

Only define the symbols if not previously defined.
