integ-cli: fix clock skew against remote test daemon 

This fixes the `docker events`-related tests as they have been
failing due to clock skew between CI machine and test daemon on
some other machine (even 1-2 seconds of diff causes races as
we pass local time to --since/--until).

If we're running in same host, we keep using time.Now(), otherwise
we read the system time of the daemon from `/info` endpoint.

Fixes pretty much all events-related tests on windows CI.
