cloud_storage_clients: add BlobNotFound check

Previously, we were checking for a `PathNotFound` result in
`abs_client::do_delete_path()`. However, we should also check for
`BlobNotFound`, so that `error_code::key_not_found` errors don't
propagate from the `abs_client` to the `remote` object.

(cherry picked from commit c85024a)
