crun: introduce crun (OCI runtime provider)
crun: introduce crun (OCI runtime provider)

Create the initial recipe to provide crun as an alternative OCI runtime
provider.

This currently has a depdenency on seccomp, but it would be nice if we
can make that optional in the future to avoid pulling in all of
meta-security as a dependency.

Example:

  % skopeo copy docker://busybox oci:busybox-oci:latest
  % mkdir busybox-bundle
  % oci-image-tool create --ref platform.os=linux busybox-oci busybox-bundle
  % cd busybox-bundle/
  % rm config.json
  % runc spec
  % runc run foo
^D
  % crun run foo
^D
