Vincent Demeester c502fb49dc Use *check.C in StartWithBusybox, Start, Stop and Restart…
… to make sure it doesn't fail. It also introduce StartWithError,
StopWithError and RestartWithError in case we care about the
error (and want the error to happen).

This removes the need to check for error and make the intent more
clear : I want a deamon with busybox loaded on it — if an error occur
it should fail the test, but it's not the test code that has the
responsability to check that.
