net/nettest: de-flake tests on Windows

Browse Source 
Windows has a low resolution timer.
Some of the tests assumed that unblock takes effect immediately.

Consider:

t := time.Now()
elapsed := time.Now().After(t)

It seems plausible that elapsed should always be true.
However, with a low resolution timer, that might fail.

Change time.Now().After to !time.Now().Before,
so that unblocking always takes effect immediately.

Fixes #873.
