Ignore x-amz-te: append-md5 request header

This header requests that the server add a trailing MD5 checksum to the response body. However, if the X-Amz-Transfer-Encoding: append-md5 response header is missing then the AWS Java SDK v2 will ignore its absence. So ignoring the request header works for now. Fixes #414.
