[PATCH stalld 16/52] tests: Remove redundant pkill from cleanup

The cleanup function uses pkill -9 -f starvation_gen to kill all
starvation generator processes system-wide. This is redundant
because the CLEANUP_PIDS array already tracks every spawned
process by PID and terminates them individually.
