Add support for firmware updates via RAUC on aarch64. The created RAUC
bundle (images/infix-$BR2_ARCH.pkg) is signed with the same key used
to sign the raw FIT image.
On amd64, we use grub instead of U-Boot, because yours truly can't
figure out how to handle ACPI handover to the kernel.
The resulting image is now called disk.img instead of the old mmc.img,
since we can use it over any interface (e.g. virtio or SCSI).
Now that we only support mmc and squash in `make run` we should make
sure the reference platform works as well as aarch64.

This change checks¹ if the system does not have a br0 interface, creates
a default one consisting of all switch ports in VLAN 1 of br0.
On top of br0 a vlan1 management interface is created with DHCP address.
For emulation and test purposes, a way to supply tap interfaces from
Qemu, and pass off as if they were regular switch ports, is added.
____
¹ obviously a better way to detect a factory-reset device is needed,
not all systems running infix will need or want a br0 interface.

This change replaces the BusyBox ifup/ifdown applets with the full-blown
ifupdown2 package. To get it fully working we also need to enable a few
missing kernel features: ipv4 + ipv6, multiple routing tables, and some
netfilter features. We take the opportunity to sync kernel features in
between the two archs as well.

Set up bridge first:
root@infix:~# ip link set dev eth0 up
root@infix:~# ip link set dev eth1 up
root@infix:~# ip link set dev eth2 up
root@infix:~# ip link set dev eth3 up
root@infix:~# ip link add name br0 type bridge
root@infix:~# ip link set dev eth0 master br0
root@infix:~# ip link set dev eth1 master br0
root@infix:~# ip link set dev eth2 master br0
root@infix:~# ip link set dev eth3 master br0
Start MRP server and add a configuration:
root@infix:~# mrp_server &
root@infix:~# mrp addmrp bridge br0 ring_nr 1 pport eth0 sport eth1 ring_role mrm
root@infix:~# mrp addmrp bridge br0 ring_nr 2 pport eth2 sport eth3 ring_role mrm
root@infix:~# mrp getmrp
bridge: br0 ring_nr: 1 pport: eth0 sport: eth1 ring_role: MRM ring_state: CHK_RO
bridge: br0 ring_nr: 2 pport: eth2 sport: eth3 ring_role: MRM ring_state: CHK_RC
Once all rings are set up:
root@infix:~# ip link set dev br0 up

The Buildroot linux_defconfig doesn't have CONFIG_OVERLAY_FS, which we
need for our shared rootfs overlay.
