Makefile: Add DOCS for building files/HOWTO.html

The rules are more general though; any new *.txt file in doc/ that
doesn't match *.?.txt or one of the explicitly-listed *.generated.txt
files will be automatically built and distributed.

The generated `files/docbook-xsl.css` is a side effect of the xhtml
target.
