commit: https://git.buildroot.net/buildroot/commit/?id=5ec9542415c92584fe0b986feea6326375bd63b6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This patch adds runtime testing of the OCI archive created by the
sloci scripting. It launches a containerd instance, imports, and
runs the OCI container.
The existing QEMU AARCH64 kernel config was extended to enable common
options used by a container runtime (cgroup and overlayfs).
