Give the DeleteMessage permission to our SQS apps

We were seeing "permission denied" errors in the ingestor logs
because when it went to delete a message from the SQS queue, it
wasn't allowed.  This ensures that messages are deleted from the
SQS queue after the ingestor/ID minter have processed them.
