This commit bump the kernel version of this docker test (5.4->6.18), and thus
fixes several issues preventing the Docker Compose runtime test from
succeeding due to this bump:
Kernel Infrastructure:
The Docker daemon failed to start because the 'nat' table could not
be initialized. This was due to missing legacy Netfilter support.
- Enable CONFIG_NETFILTER_XTABLES_LEGACY to support iptables nat table.
- Enable CONFIG_NAMESPACES and CONFIG_USER_NS for container isolation.
- Enable CONFIG_TUN and CONFIG_VETH for container networking.
- Enable CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC for easier debugging.
Build Fixes:
While building the kernel tools, the libelf header was missing because
objtool was not handled correctly for this kernel version. This resulted
in a fatal error: "gelf.h: No such file or directory".
- Select BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y to build host-libelf.
Resources and Stability:
The previous 512MB of RAM was tight for the stack (Kernel +
Docker + Containerd + Python), potentially leading to Out-Of-Memory kills.
Idem for the disk size for Docker images/layers storage.
- Increase QEMU RAM to 1024MB (-m 1024M).
- Increase rootfs size to 1024MB.
- Switch to EXT4 (BR2_TARGET_ROOTFS_EXT2_4=y) for better stability
and modern feature support required by Docker's storage drivers.
Test Script Adjustments:
- Update rootfs path in the test script to point to rootfs.ext4.

Since commit 947dbc92a2 the Bootlin
stable toolchain uses headers 5.4, which can lead to build outputs
incompatible with older kernels. Update to the latest 5.4 kernel to
avoid this. The kernel config is updated according to the requirements
of current Docker, runc, and crun.
Additionally switch the CPU of the test VM to Haswell, to avoid
dockerd failing to start with a "This program can only be run on AMD64
processors with v3 microarchitecture support" error.

Since commit 0390777bfa (package/docker-engine: needs some kernel
options), docker-engine now automatically ensures the needed kernel options
are enabled, so drop the explicit options from the kernel config.

Build for x86-64 as public containers in general are only available for
x86-64. Docker needs a number of kernel options enabled, so use a custom
kernel config based on the qemu one.
Docker needs entropy at startup, so enable the virtio-rng-pci device to
expose entropy to the guest. The default RAM amount (128M) is not enough to
run docker / docker-compose, so bump to 512MB.
