cryptohome: Have a specific error for vault recreation trigger.

Having unspecific MOUNT_ERROR_FATAL is too abstract for people to
realize it may cause a destructive behaviour. Here we introduce a
dedicated error to trigger the re-creation if all keys are unparsable or
broken in another way. This change reduces the amount of cases
triggering the recreation - e.g. just missing output vk structure is an
error but, but not a reason for vault re-creation.
