Subject: [PATCH] Fix atf-sh/atf_check_test:flush_stdout_on_death

The test atf-sh/atf_check_test:flush_stdout_on_timeout was flaky as it
was playing solely with time.  Fix this by making the test more robust
and rename it while we are at it: there is nothing left about "timeouts"
in this test, considering that ATF itself does not enforce deadlines
any longer.

Fixes FreeBSD PR 197060.
