st: imágenes con el protocolo de kitty (vistas previas en yazi)

Se rehace st desde el 0.9.3 original con los parches:

- kitty-graphics (oficial, 20251230): muestra imágenes en la terminal;
  yazi lo detecta solo y no necesita ueberzugpp. Ya incluye anysize, así
  que ese parche sobra.
- alpha, sin cambios.
- glyph-wide-support: los iconos anchos (Nerd Font) no se cortan.
- ligatures, con los conflictos resueltos como en la rama
  graphics-with-patches de st-graphics, quitando lo de boxdraw.

config.h lleva los mismos cambios de antes sobre el config.def.h nuevo.
Necesita imlib2-devel para compilar.
