Add --debian-only option to build.sh for rebuilding Debian packages only

- Added --debian-only flag that skips Python/C building and SSL/logo generation
- Only performs Debian package building and dependency checking
- Useful for quick package rebuilds after Debian packaging changes
- Maintains all existing functionality when used with --debian
- Provides focused output showing only Debian package results
