backup-auth creates files with insecure permission

[znz]

dokku postgres:backup-auth creates world-readable files.
I think AWS_SECRET_ACCESS_KEY should not be world-readable at least.

vagrant@dokku:~$ dokku postgres:backup-auth lolipop MINIO_ACCESS_KEY_ID MINIO_SECRET_ACCESS_KEY us-east-1 s3v4 https://YOURMINIOSERVICE
vagrant@dokku:~$ ls -al /var/lib/dokku/services/postgres/lolipop/backup/

What should be the correct permissions on these files?

This should be resolved by dokku/dokku-postgres#206
