fix: live-boot install — avoid chroot, use dpkg extraction fallback

Browse Source 
The chroot /installer command fails inside the CI container because
the container exits after debootstrap completes (set -e + container
boundary). The chroot then runs on the host where /installer doesn't
exist.

Fix: use apt-get with Dir overrides first, fall back to dpkg-deb -x
extraction of live-boot .deb files directly into the installer root.
This bypasses chroot entirely and is more robust in container-in-
container environments.
