fix: make metadata generation tolerant to missing architecture packages

When an exporter doesn't support all architectures (e.g., gpfs_exporter
only supports amd64), the metadata scripts should skip those combinations
instead of failing with exit 1.

Changed behavior:
- Exit 0 instead of exit 1 when no packages found
- Display warning instead of error
- Allows publish-metadata job to complete successfully
