nixos/hadoop: Replace users.extra{Users,Groups}

In fff5923686 all occurences of
users.extraUsers and users.extraGroups have been changed tree-wide to
users.users and users.group. In the meantime the hadoop modules were
introduced via #41381 (060a98e9f4).

Unfortunately those modules still use users.extraUsers, which has been
renamed a long time ago (14321ae243, about
three years from now), so let's actually rename it accordingly as well.
