Test suspend and resume cycles of the TPM front- and backend.
Now that sysfs is mounted in the RAM disk of the test environment, the
test code does not need to do this anymore. This patch also simplifies
previous tests and the APIs used there. If prerequisites are not met
(vtpm manager not running) the patch will 'skip'.
