B2 gateway S3 compat: return MD5 hash as ETag from PutObject (#9183)

- B2 does actually return an MD5 hash for newly uploaded objects
  so we can use it to provide better compatibility with S3 client
  libraries that assume the ETag is the MD5 hash such as boto.
- depends on change in blazer library.
- new behaviour is only enabled if MinIO's --compat mode is active.
- behaviour for multipart uploads is unchanged (works fine as is).
