fix(iso): auto-detect kernel ABI at build time instead of pinning

Browse Source 
DEBIAN_KERNEL_ABI=auto in VERSIONS — build.sh queries
apt-cache depends linux-image-amd64 to find the current ABI.
lb config now uses linux-image-amd64 meta-package.

This prevents build failures when Debian drops old kernel packages
from the repo (happens with every point release).
