ARROW-1347: [JAVA] Return consistent child field name for List Vectors
This makes the child fields of ListVector have consistent names of
`ListVector.DATA_VECTOR_NAME`. Previously, an empty ListVector would have a
child name of `ZeroVector.name` which is "[DEFAULT]".

> The child field for List type has the field name "$data$" in most cases. In
> the case that there is not a known type for the List, currently the
> getField() method will return a subfield with name "DEFAULT". We should make
> this consistent with the rest of the cases.
