    podman: get cpus allowed list only when isolcpus in cmdline

    When building the podman command, only get cpus allowed list when there
    is isolcpus in the /proc/cmdline otherwise skip the argument.

    Note: re-working the Mocks for cpu affinity so we can properly test the
    /proc/cmdline reads.
