s3: Move from goamz to minio-go

goamz is not maintained anymore move to maintained
library like `minio-go`.

`minio-go` supports S3 and many other s3 compatible
vendors. `minio-go` also supports both Signature V2 and
Signature V4. This in-turn would enable `transfer.sh`
to be able to use many different S3 compatible storage
vendors.

Fixes #5
