This commit simplifies the ETag decryption and size adjustment
when listing object parts.
When listing object parts, MinIO has to decrypt the ETag of all
parts if and only if the object resp. the parts is encrypted using
SSE-S3.
In case of SSE-KMS and SSE-C, MinIO returns a pseudo-random ETag.
This is inline with AWS S3 behavior.
Further, MinIO has to adjust the size of all encrypted parts due to
the encryption overhead.
The ListObjectParts does specifically not use the KMS bulk decryption
API (4d2fc530d0) since the ETags of all
parts are encrypted using the same object encryption key. Therefore,
MinIO only has to connect to the KMS once, even if there are multiple
parts resp. ETags. It can simply reuse the same object encryption key.
