Adding `metadata.data_source.permissions_data` to
sharepoint-with-permissions.sh --metadata-exclude to prevent sharepoint
deprecation warning from ruining test.
Updating expected-structured-output
As per Ahmet's comment. We do want to check sharepoint permissions
metadata at some point. But that will take a separate type of test. A
file diff test is too unstable. Permissions checking will be later down
the road.
