base.install: Fix apt components

[dsavineau]

• 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/
