Make minio package support legacy MD5 checksum (#23768)

A feedback from discord:
1090185427

Some storages like:

 * https://developers.cloudflare.com/r2/api/s3/api/
 * https://www.backblaze.com/b2/docs/s3_compatible_api.html

They do not support "x-amz-checksum-algorithm" header

But minio recently uses that header with CRC32C by default. So we have
to tell minio to use legacy MD5 checksum.

I guess this needs to be backported because IIRC we 1.19 and 1.20 are
using similar minio package.


The minio package code for SendContentMD5 looks like this:
