[git commit] unit-tests: remove unnecesary field from struct bbunit_listelem

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=d077565bb27966c47ea6f0e9de092133954b5807
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

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.
