Since all of the chamelium calls are blocking, we need to be able to make suspend/resume tests with it multi-threaded. As such, it's not the best idea to rely on igt_system_suspend_autoresume() for skipping tests on systems without suspend/resume support since we could accidentally leave the thread controlling the chamelium running after the test gets skipped.
