Curl_ipv4_resolve_r: only set AI_CANONNAME when needed
As reported in bug report #2987196, the code for ipv6 already did the setting of this bit correctly so we copied that logic into the Curl_ipv4_resolve_r() function as well. KRB code is the only code we know that might need the cannonical name so only resolve it for such requests!
