mkfs.ubifs: do not override root inode permissions
When mkfs.ubifs is used with -r dir, it does not make the root UBIFS inode uid/gid/permissions to be equivalent to dir's permissions, but it makes root inode permissions to be equivalent to uid = git = 0 (root) and permissions = u+rwx go+rx. Unfortunately, we cannot simply fix this bug, because mkfs.ubifs is already used in production. Thus, we have introduce --squash-rino-perm option which is the default and it preserves the old mkfs.ubifs behavior. We also introduce --nosquash-rino-perm option which fixes mkfs.ubifs behavior. If none of these options is used, we print a warning. The plan is to make everyone use one of these options, then make --nosquash-rino-perm to be the default and remove the warning, and then eventually deprecate and remove both options.
