Aligned the package layout with the concurrent Debian packaging
conventions. Moved package files under 'debian/all/' to avoid
duplication across OS builds and removed legacy paths under 'debian/'.
Updated related build references to ensure compatibility across all
supported OS codenames.
Test Plan:
PASS master bullseye build
