Jonathan Wakely 573c2ffd3c libstdc++: Value-initialize objects held by EBO helpers [PR 100863] 
The allocator, hash function and equality function should all be
value-initialized by the default constructor of an unordered container.
Do it in the EBO helper, so we don't have to get it right in multiple
places.
