    Avoid access beyond memory bounds in pthread_attr_getaffinity_np

    Resolves BZ #15618.

    pthread_attr_getaffinity_np may write beyond bounds of the input
    cpuset buffer if the size of the input buffer is smaller than the
    buffer present in the input pthread attributes.  Fix is to copy to the
    extent of the minimum of the source and the destination.
