Drop xiterm dependency

[hramrach]

fbiterm (xiterm) is a dead project - the latest change is from 2004. It does not appear to work well on recent kernels with several drivers. Factory has mlterm-sdl2 and SDL2 updated to not cache kernel keymap, both are projects actively maintained upstream. Now also fails to build with gcc 14

We know very well that it's been a dead project for many years; but it was pretty much the only reliable way to get i18n support for the YaST NCurses UI for languages outside the Latin1 (Western Europe) and parts of the Latin2 (Eastern Europe; CZ, PL, HR) world. In particular, CN, KO, JP were problematic without it.

Dropping fbiterm would pretty certainly mean no more support for Chinese, Japanese, Korean in YaST NCurses; and I am unsure how well cyrillic locales (Russian, Ukrainian, Bulgarian etc.) or Greek would work.

This is not enough and will just cause installation-images builds to fail. Let's resolve the discussion in that bugzilla first.
