MINOR: stream: remove the cpu time detection from process_stream()

It was not as efficient as the watchdog in that it would only trigger
after the problem resolved by itself, and still required a huge margin
to make sure we didn't trigger for an invalid reason. This used to leave
little indication about the cause. Better use the watchdog now and
improve it if needed.

The detector of unkillable tasks remains active though.
