[PATCH 1/2] Fix preseeding support

[otavio at ossystems.com.br (Otavio Salvador)]

From: Otavio Salvador <otavio@ossystems.com.br>

Preseeding wasn't calling apt-get with --force-yes hence aborting
chroot building. Besides, we add support to identify a wrong or non
existent preseeding file warning the user when it's the case.
