[PATCH:xorg-docs] Add fop.xsl stylesheet to set fonts in ps & pdf output

[Alan Coopersmith]

Since a number of documents, especially the credits section in the Release
Notes, use characters not found in the fop default base PostScript fonts,
add a stylesheet for the fop generated documents to use the free DejaVu and
GNU Unifont fonts which cover a much wider range of characters.
