Switch to new sigs-based auth in VSS integration tests

When we added the trivial sigs-based authentication scheme in VSS,
we made it the default if no other authentication scheme was
configured and default features are enabled.

This broke our integration tests as we were expecting no
authentication to be required in such a case.

Here we fix this by switching to the new sigs-based auth scheme,
removing `store_id`s to demonstrate client isolation while we're at
it.
