    sys/cpu/x86_64: Expose CPUMASK macros to userspace without _KERNEL_STRUCTURES
    
    Userspace programs other than /sbin/usched may use cpu affinity,
    as the syscall was added for userspace programs to control it,
    so it should not require _KERNEL_STRUCTURES.
    
    Also note that cpumask_t which is a structure used by CPUMASK
    macros doesn't require _KERNEL_STRUCTURES.
    
    Confirmed the change doesn't break buildworld and buildkernel/LINT64.
    
    (I actually had compile-time issues with fio while trying to add
    cpu affinity support, and ended up copy-pasting CPUMASK macros
    to a DragonFly specific header in fio source without defining
    _KERNEL_STRUCTURES)
