CL 33239 changed the polling loops from using sched_yield to a sleep
for 1/1000 of a second. The loop counters were not updated, so failing
tests now take 100 seconds to complete. Lower the loop counts to 5
seconds instead.

Apparently when GOMAXPROCS == 1 a simple sched_yield in a tight loop is
not necessarily sufficient to permit a signal handler to run. Instead,
sleep for 1/1000 of a second.
Fixes#16649.

After a failure on the build dashboard I tested testcarchive test 2 and
found that it failed an average of 1 in 475 runs on my laptop. With
this change it ran over 50,000 times without failing. I bumped up the
other iteration limits to correspond.

Only install signal handlers for synchronous signals that become
run-time panics. Set the SA_ONSTACK flag for other signal handlers as
needed.
