libstdc++: Support N3644 "Null Forward Iterators" for testsuite iterators

Comparing value-initialized forward_iterator_wrapper<T> objects fails an
assertion, but should be valid in C++14 and later.

* testsuite/util/testsuite_iterators.h (forward_iterator_wrapper): Add
equality comparisons that support value-initialized iterators.
