shutils/cgroups: Don't fail when racing with process exit

Browse Source 
If a process is added to $PIDS but then exits before the
cgroups_task_move invokation finishes, then echoing its PID to
cgroups.procs results in an I/O error. If that process is the last in
$PIDS, then that failing echo command is the last of the function, so
the script exits with an error and devlib raises an exception.

Add `|| true` to avoid this problem.
