Better to use silent bool.

Nydusify provides a fsViewer to view the file system in the Nydus image. The fsViewer will pull image's bootstrap according to its url, and it will mount the file system to pointed path. Users can view the file system then. For example, they can ran `$ trivy fs mount-path` to scan the whole image. Signed-off-by: YushuoEdge <[email protected]>
