support/testing/tests/fs: test OCI format

Browse Source 
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).
