Nick Craig-Wood e5974ac4b0 s3: use PutObject from the aws SDK to upload single part objects
Before this change rclone used presigned requests to upload single
part objects. This was because of a limitation in the SDK which didn't
allow non seekable io.Readers to be passed in.

This is incompatible with some S3 backends, and rclone wasn't adding
the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` header which was
incompatible with other S3 backends.

The SDK now allows for this so rclone can use PutObject directly.

This sets the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` flag on the PUT
request. However rclone will add a `Content-Md5` header if at all
possible so the body data is still protected.

Note that the old behaviour can still be configured if required with
the `use_presigned_request` config parameter.

Fixes #5422
