[PATCH v4 03/12] doc: simplify version passing

[Felipe Contreras <felipe.contreras@gmail.com>]

The code to pass the version of the man page comes from 2007:
7ef195ba3e (Documentation: Add version information to man pages,
2007-03-25). However, both asciidoc and asciidoctor already do this by
default.

Asciidoctor doesn't read manversion, but there's no need since both
tools just join mansource and manversion.

Let's do that ourselves and get rid of a bunch of code.
