curl: wolfSSL backend disables hostname verification when CURLOPT_SSL_VERIFYPEER is 0

Summary When curl is built against wolfSSL, setting CURLOPTSSLVERIFYPEER=0 causes a hostname-mismatched certificate to be accepted even though CURLOPTSSLVERIFYHOST remains at its default enabled setting. I built wolfSSL from source, built curl against it, and connected to a TLS server presenting ...
