`security_opt` does not support option `seccomp=unconfined`

When creating a container using the library I am not allowed to pass the `seccomp=unconfined` security option. We receive the following error: `creating container storage: Bad label option "seccomp=unconfined", valid options 'disable' or 'user, role, level, type, filetype' followed by ':' and a value)`.

Is this something that can be fixed in this library or is more an issue for the `podman` repo?

Note that `podman compose` creates the container with the `seccomp=unconfined` security option without issues.
