docbook.am: embed css styles inside the HTML HEAD element

Rather than referring to the external xorg.css stylesheet, embed the content
of the file in the html output produced. This is accomplished by using
version 1.10 of xorg-xhtml.xsl.

This makes the whole html docs tree much more relocatable.
In addition, it eliminates xorg.css as a runtime file which makes
xorg-sgml-doctools a build time only package.
