New linuxwacom version in rawhide includes the (kind of crappy) config tools.
This ends up pulling in tcl and tk to the live images adding a significant
amount of space (that we don't have to spare).
We should probably either continue not shipping the crappy tools are at the very
least, split them into a subpackage
The tk config tools were removed in linuxwacom 0.7.9.8-2. There's an ncurses
dep in the config tools too, but that's probably not worth worrying about.
