Route s3.asxp.io to Garage

The data is copied and verified and both apps sign with their Garage
keys, so send s3.asxp.io to Garage's S3 API. MinIO loses its route and
stays up, unrouted, as the way back.

Garage answers no anonymous S3 request. Unsigned GET and HEAD of
/public/<key> go to its web endpoint instead, with the Host header the
endpoint picks the bucket by, so the links handed out so far keep
working. Signed requests for that bucket still reach the S3 API.
