CONFIG_NF_TABLES_NETDEV, CONFIG_NF_TABLES_IPV4, CONFIG_NF_TABLES_IPV6 and
CONFIG_NF_TABLES_BRIDGE to 'y', and related options to 'm'.
When running qemu-img from (gnu system vm) with an aarch64 kernel, mounting
ext4 partitions fails because no modprobe of ext4 module is made. Like for
other kernel configs, provide built-in support for ext4 partitions.
* gnu/packages/aux-files/linux-libre/5.2-arm64.conf: Enable built-in ext4,
like in intel and armhf configs.
