Set child subreaper attribute

When the hydra loader is terminated, the parent process ID of the
application that is launched using the loader process is created by
the hydra loader is changed to the launchpad-process-pool.
Currently, the hydra loader is terminated, the application is always running
as zombie process. After this patch is applied, even though the hydra load
is terminated, the launchpad-process-pool gets the SIGCHLD signal when
the application is terminated.
