Makefile: Use asciidoc and Pandoc to generate MediaWiki doc versions

We need this because hosting content under:

  https://www.gentoo.org/proj/

is deprecated, with per-project documentation migrating to the wiki [1]

* `--attribute 'toc!'` disables AsciiDoc's table of contents [2],
  which Pandoc doesn't like.
* The Pandoc invocation is about as basic as it gets [3].
