Fix init script setup and preserve build artifacts

- Copy configs/init as /sbin/init instead of creating symlink to zinit
- Remove automatic cleanup of build artifacts - always preserve for incremental builds
- Allows rebuilding initramfs with existing components
- Use ./scripts/clean.sh to manually clean when needed
