Fix 77264: curl_getinfo returning microseconds, not seconds

Fix 77264: curl_getinfo returning microseconds, not seconds

Since curl 7.55.0, libcurl introduced new constants to return
more sensible variable types with curl_getinfo.

When curl_getinfo with no option was called, and curl >= 7.55.0, some
of the result were returned as int when they where returned as float
in previous versions. This commit remove this BC Break.

If someone still want to use more sensible variable types, it's always
possible to call curl_getinfo with newer constants.
