[PATCH] tests: Accept any core if no core with the "correct" pid can be found.

[PATCH] tests: Accept any core if no core with the "correct" pid can be found.

[Mark Wielaard]

In some containers our view of pids is confused. We see the container
pid namespace, but the core is generated using the host pid namespace.
Since tests are run in a new fresh directory any core here is most like
is ours.
