userformat_want_item(): mark unused parameter

This function is used as a callback to strbuf_expand(), so it must
conform to the correct interface. But naturally it doesn't need to touch
its "sb" parameter, since it is only examining the placeholder string,
and not actually writing any output. So mark the unused parameter to
silence -Wunused-parameter.
