tests: Fix common test failures in GrlNet tests

The small-delay test fails fairly often, about 20% of the time for a 100
runs on a non-loaded machine.

We're lucky it doesn't happen more often, as g_timeout_add_seconds() as
used by grl-net-wc.c will ultimately use g_timeout_set_expiration()
which might round up timeouts to the above second:
"
/* We want the microseconds part of the timeout to land on the
 * 'timer_perturb' mark, but we need to make sure we don't try to
 * set the timeout in the past.  We do this by ensuring that we
 * always only *increase* the expiration time by adding a full
 * second in the case that the microsecond portion decreases.
 */
"

Bump the threshold to a full second, and verify by raising the delay
in the grl_net_wc_set_throttling() call.
