    ve/sched: put move_task_groups() under CONFIG_CFS_CPULIMIT
    
    This was found while tring to compile the kernel with a stock
    config (i.e. no CONFIG_BEANCOUNTERS, CONFIG_VE etc.) and
    boot it on IBM Power8.
    
    =============================================================
    
    Function move_task_groups() is not defined if CONFIG_CFS_CPULIMIT
    is not set, so compiler complains.
    
    This is a fix to commit 51fd1aec7.
