templates: support linking to main help page

Currently, the "helptopics" template assumes it is only used as the
main index and therefore doesn't hyperlink "help" in the navigation
list. Sub-topics will introduce an additional consumer of this
template. So teach the template to hyperlink the "help" navigation
entry when necessary.
