Makefile.kicad: added generation of a positioning for the SMT fab

- Makefile.kicad ($(NAME)Front.pos): --origin does nothing with --pos;
  removed it
- Makefile.kicad ($(NAME)-pos.csv): use pos2fab to generate a positioning
  file for the SMT fab
- Makefile.kicad (clean): remove $(NAME)Front.pos and $(NAME)-pos.csv
