Sometime between 10th and 23rd of Feb. 2020, the behavior of crun changed. Upon consulting with Giuseppe, the podman run tests for `device-read-*` and `device-write-*` do not depend on the container output for success, only the exit code. Add a comment and conditional regarding this in case of cgroupsv2. Also noted that these tests will likely require future refactoring/simplification. Signed-off-by: Chris Evich <cevich@redhat.com>
