Update fault for bullseye/Trixie

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
PASS: AIO-SX Deploy
