fix: missing cleanup of tmp folders in NAS gateway setup (#13124)

console service should be shutdown last once all shutdown
sequences are complete, this is to ensure that we do not
prematurely kill the server before it cleans up the

`.minio.sys/tmp/uuid` folder.

NOTE: this only applies to NAS gateway setup.
