initial features.in/cleanup

This is a sort of anti-feature which removes and not builds;
still with mkimage-profiles' approach we can at least build
up the removal procedures as well.

It's what triggered the tagged scripts, BTW.

+Эта фича вместо созидания занимается выкидыванием лишнего
+(например, части модулей инсталятора из установленной системы).

+По возможности стоит работать над дизайном инфраструктуры
+и пакетной базой так, чтобы ставить-удалять приходилось как
+можно меньше.  В идеале такой антифичи не должно быть вовсе :)
