t-hashmap: mark unused parameters in callback function

The t_intern() setup function doesn't operate on a hashmap, so it
ignores its parameters. But we can't drop them since it is passed as a
pointer to setup(), so we have to match the other setup functions. Mark
them to silence -Wunused-parameter.
