MDEV-35581 On servers linked against WolfSSL SSL_Cipher and SSL_cipher_list are always the same

emulate OpenSSL behavior in WolfSSL:
* use wolfSSL_get_cipher_list(i) for SSL_get_cipher_list(ctx, i),
  not wolfSSL_get_cipher_list_ex(ctx, i), which returns only
  the cipher used in the current connection.
