don’t test exitstatus when it is unknown

apparently on some Ruby 1.8.7 installs, open3 doesn’t return an exit
status, and that includes all Travis installs of 1.8.7. :/ these tests
all pass (while checking exit status) on my machine, but they shouldn’t
fail if the Ruby on Travis isn’t able to provide exitstatuses.
