update links for DocBook repository (#122)

The project moved to GitHub from Sourceforge a number of years ago.
This updates references to the project to point at this new home and CDN.
However, the links in the docbook-xsl/*.xsl files remain pointing at sourceforge
as they are reliant on target distros to update their respective catalog.xml
to include these new links. Given the huge amount of existing software that
will continue to use the SF links, it's unlikely these will break anytime soon at least.
