util: make sure fd refers to regular file or directory when applying file attributes

Before invoking file system ioctls we need to make sure that the
specified fd actually refers to a file system object, and not a device
node or similar. Otherwise we might by accident invoke unrelated device
driver ioctls. For example, DRM ioctls use the same ioctl numbers as the
various file system ioctls.
