dowan gullient 3430d8200e support/testing: test_docker_compose: Bump kernel version to last LTS (6.18) ...

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.
