fs: ubifs: Add authentication support
This adds UBIFS authentication support. For now, we do not do
any authentication even on authenticated UBIFS images. Since
this behaviour is not what the user normally expects when mounting
authenticated images we only do this when the user explicitly allows
it in "global.ubifs.allow_authenticated_unauthenticated". If the
flag is false then we refuse mounting such an image and return -EPERM
instead.
