[CRIU] [PATCH] parasite: wait for any child process

[Andrey Vagin]

If parasite exited unexpectedly, CRIU gets SIGCHLD and handles it.
In sigchld handler we need to wait any child process.
Currently criu waits neighbours in its group, but a dumped
processes is in another group usually. Here is a typo.
