files: overlayfs-etc: add overlay mount options to preinit
Overlayfs-etc is useful if the rootfs is read-only. One reason to have
the rootfs read-only is to allow image based updating.
Image based updating will change the underlying root file system, which
is unsupported by overlayfs when with some mount options [1].
This disables those options.
