cooker: generate OCI seccomp profile

Generate the OCI seccomp profile instead of directly the BPF filter. The
seccomp profile will be used consquently by the container runtime as
input in order to generate the BPF filter.

Example with mknod:
$ seitan-cooker -g /tmp/gluten -p /tmp/scmp_prof.json -s seccomp.json -i demo/mknod.hjson
$ seitan -s /tmp/seitan.sock -i /tmp/gluten
$ podman run --cap-drop ALL
  --security-opt=seccomp=/tmp/scmp_prof.json  \
  --annotation run.oci.seccomp.receiver=/tmp/seitan.sock  \
  -ti fedora   \
  sh -c 'mknod /dev/lol c 1 7 && ls /dev/lol'
/dev/lol
