Michael Eischer ce89018902 Fix data race in blob_saver 
After the `BlobSaver` job is submitted, the buffer can be released and
reused by another `FileSaver` even before `BlobSaver.Save` returns. That
FileSaver will the change `buf.Data` leading to wrong backup statistics.

Found by `go test -race ./...`:
