    Kconfig.openvz: force CGROUP_PERF if compiling VZ Containers code
    
    The perf_event_open() syscall is available from Containers.  The
    CONFIG_CGROUP_PERF option is set in current OpenVZ kernel configs, but let's
    force-enable it if CONFIG_VE is enabled to prevent possible non-secure kernel
    config if someone rebuilds the kernel with own config.
