LU-12802 tests: speedup cleanup of racer

After racer test survives for a given time, it starts to cleanup.
And the parent racer.sh script waits the child racer/racer.sh
to exit. However sometimes, somehow, this stucks for a long time.
Sending a signal to remaining dd(or other) processes will wake up
the wait in parent racer.sh script immediately.
