test/lib: Move screen-scraping setup and layout functions to _ugly files

I'm going to add yet another one of those, for which I have no quick
solution. It's a regression in some sense, but at least if we make
this regression more observable and defined, it should be easier to
find a comprehensive solution later, within this or another testing
framework.
