[PATCH v2 5/7] Added do_finalize_image task.

[Benedikt Niedermayr <benbrenson89@googlemail.com>]

This taks does two things:
- Create a snapshot for the current Isar repository after build has finished.
- Add remote repositories to apt source files.
  Those files where not created, since multistrap only pulls packages from local mirrors.

Todos:
- multistrap-*.list files are hardcoded. This should be fixed in future, since different distributions
  refer to different repositories.
