[CRIU] [PATCH 1/7] tests: only wait for the pid we spawned

[Tycho Andersen]

In the next patch, we'll introduce an option to allow for leaving zombie
processes in the pid ns for the test so that we can test the behavior of
zombies. Let's not reap everything after restore, since we'll reap the
restored zombies as well.
