fix -h|--help component script man page redirection

the frontend handles -h|--help directly and correctly redirects to the
man page.

component scripts however fail to load the correct manpage because they
are being directed to `man <script>` instead of `man lb script`.

(affects the top level commands and major build stages which actually have
man pages; the low level components don't and so will always fail anyway).
