docs/asciidoc: call $(pkgname) and $(pkgdir) in a single place

Like for all the package infrastructures, retrieve the package name and
directory in the front-end macro-variable, rather than everywhere in the
backend macro.

This allows us to clean up the ASCIIDOC macro, by removing all the calls
to $(pkgname) and $(pkgdir), and to UPPERCASE (which made the macro a
bit difficult to read.)
