Subject: [PATCH] s3: fix missing "tier" metadata

Before this change if the storage class wasn't set on the object, we
didn't set the "tier" metadata.

This made it impossible to filter on tier using the metadata filters.

This returns the "tier" metadata as STANDARD if the storage class
isn't set on the object.
