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.
