Subject: [PATCH] drive: fix copying Google Docs to a backend which only
 supports SHA1

When copying Google Docs to Backblaze B2 errors like this would happen

    ERROR : test.docx: Failed to calculate src hash: hash type not supported
    ERROR : test.docx: corrupted on transfer: sha1 hashes differ src

This was due to an oversight in

8fd66daab671bb98 drive: add support of SHA-1 and SHA-256 checksum

Which omitted to change the base object (which includes Google Docs) so
that it supported SHA-1 and SHA-256.
