Subject: [PATCH] local-up-cluster: avoid "No such process" messages when
 cleaning up

Killing processes in cleanup is racing with those processes
terminating by themselves when aborting local-up-cluster.sh with
CTRL-C. That leads to unnecessary error messages:

  ^CCleaning up...
  kill: (21592): No such process
  kill: (21586): No such process
