unit-tests: remove unnecesary field from struct bbunit_listelem

In the initial submission struct bbunit_listelem was manipulated by
custom list functions implemented in bbunit.c. Since the tests are now
added to the list by llist_add_to_end(), which allocates the llist_t
objects behind the scenes, there's no need for the *next field.
