Ensure that madvise does not clobber vacancy data.
After calling `fiber_pool_vacancy_reset`, `vacancy->stack` and `stack` are
no longer in sync. Therefore, `fiber_pool_stack_free(&vacancy->stack)` can
do the wrong thing and clobber the vacancy data.
Additionally, when testing using VM_CHECK_MODE > 0, use MADV_DONTNEED if
possible, to catch issues w.r.t. clobbered vacancy data earlier.
