test-ww_mutex: Extend ww_mutex tests to test both classes of ww_mutexes

Currently the test-ww_mutex tool only utilizes the wait-die
class of ww_mutexes, and thus isn't very helpful in exercising
the wait-wound class of ww_mutexes.

So extend the test to exercise both classes of ww_mutexes for
all of the subtests.
