virtiofsd: Announce sub-mount points
Whenever we encounter a directory with an st_dev that differs from that of its parent, we set the FUSE_ATTR_SUBMOUNT flag so the guest can create a submount for it. Make this behavior optional, so submounts are only announced to the guest with the announce_submounts option. Some users may prefer the current behavior, so that the guest learns nothing about the host mount structure.
