Add Tizen:Common/update_meta.sh to update metadata from OBS

The script fetches:
- project config and meta (_config, _meta)
- all aggregate packages definitions (_aggregate, _meta)
- all linked packages definitions (_link files)

The script also deletes directories (packages) that have disappeared
on the remote OBS
