PM: Make warning in suspend_test_finish() less likely to happen
Increase TEST_SUSPEND_SECONDS to 10 so the warning in suspend_test_finish() doesn't annoy the users of slower systems so much. Also, make the warning print the suspend-resume cycle time, so that we know why the warning actually triggered. Patch prepared during the hacking session at the Kernel Summit in Tokyo.
