[PATCH 1/2] Documentation/Makefile: add missing dependencies on asciidoctor-extensions

["Martin Ågren" <martin.agren@gmail.com>]

I really should have caught this when I wrote 00c87bceaa
("Documentation/Makefile: add missing dependency on
asciidoctor-extensions", 2019-02-27). That commit made sure that the
xml-files depend on our Asciidoctor-specific extensions, but that just
helps for the ".txt -> .xml -> .[157]" transformations.

Because we produce the html-files directly as ".txt -> .html" -- not as
".txt -> .xml -> .html" --, we need to make the html-files too depend on
asciidoctor-extensions.rb.

There's one exception to the above paragraph. We do render
user-manual.html by going through an intermediate user-manual.xml, which
is an explicit, special-cased target. Add the missing dependency to
user-manual.xml.
