barrier: fix race in test-code
The barrier_wait_next_twice* test-cases run:
Parent: Child:
set_alarm(10) sleep_for(1);
... set_alarm(1);
sleep_for(2) ...
Therefore, the parent exits after 2+ periods, the client's alarm fires
after 2+ periods. This race turns out to be lost by the child on other
machines, so avoid it by increasing the parent's sleep-interval to 4. This
way, the client has 2 periods to run the barrier test, which is far more
than enough.
