test/thread: relax internal implementation check in error message

Queue, SizedQueue, and ConditionVariable internal implementation
should not be tied to using arrays.  Implementation details can
change and I am working on a change to remove the dependency on
arrays (as others may attempt, too) by using ccan/list for the
waiter list.

* test/thread/test_cv.rb (test_dump): remove check for Array
* test/thread/test_queue.rb (test_dump): ditto
