test/cql-pytest: test_keyspace.py: test_storage_options_local(): fix for tablets

This test expects a keyspace with local storage option, to not have a
row in system_schema.scylla_keyspace. With tablets enabled by default,
this won't be the case. Adjust the test to check for the specific
storage-related columns instead.
