base.install: Fix apt components

* Add components parameter in debootstrap for debian/ubuntu.
* Add basic components in all sources (release, updates and security):
  - Debian : main contrib non-free
  - Ubuntu : main universe multiverse
* Merge all these informations in /etc/apt/sources.list instead of split them
in /etc/apt/sources.list.d/
