Making ocropus-hocr run (matplotlib + gdk backend)

I added the gtk backend to matplotlib; if these added dependencies are
too much, we can make this optional.
ocropus: it was still missing a package: lxml

Now "./run-tests" passes. But it can't be run without DISPLAY, so
I don't run it in the builder.
