CURLINFO_CONDITION_UNMET: return true for 304 http status code

Browse source 
In libcurl, CURLINFO_CONDITION_UNMET is used to avoid writing to the
output file if the server did not transfered a file based on time
condition. In the same manner, getting a 304 HTTP response back from the
server, for example after passing a custom If-Match-* header, also
fulfill this condition.

Fixes #5181
Closes #5183
