heal: Fix deep scan failing to heal objects (#117 )
The verify file handler response format was changed from gob to msgp since two months but we forgot updating the verify handler client. VerifyFile is only called during a heal deep scan (bitrot check). HealObject() will fail in that case and will mark all disks corrupted and will return early (as unrecoverable object but it will also not be removed) It is a bit rare for HealObject to be called with a deep scan flag. It is called when a HealObject with a normal scan (e.g. new drive healing) detects a bitrot corruption, therefore healing objects with a detected bitrot corruption will fail.

 The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded web-based object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
