system tests: fix flake waiting for container to run

I have seen some system tests flake waiting for a container to
transition into a specific running state.  My theory is that
the waiting time was not sufficient on nodes under high load.
Hence, increase the waiting time.  Also replace the break with
a return to spare some cycles to redundantly compare with the
already checked state.
