Since LFS started using docbook-1.78.1, there is a lot of unused data

in the stylesheet directory. Basically, a whole docbook-stylesheet is
there, while we need only fo and xhtml (+ some common dirs). Each time
we checkout the repo, we have to download this whole thing, which is by
far the biggest part of the repo (~33 M). By removing unused cruft,
this could be down to ~12 M.

Of course, it would be even better to remove completely the stylesheets
and use host ones (repo size down to 2M). but let's do this first, it is
easier :)
