numademo: fix error on 32bit system

Error Info on 32bit:
root@intel-x86:~# numademo -t -e 1M
Configured Nodes does not match available memory nodes

That's because sizeof(long)=4Word, but sizeof(long long)=8Word
on 32bit. So (long long) assigning to (long) maybe cause overflow.

{
    ...
    long sz = numa_node_size64_int(node, &f2);
    return sz;
    ...

long long numa_node_size64(int node, long long *freep)
{
    ...
}
