scripts/setup: allow specifying numa node to allocate hugepages on

Browse Source 
The setup.sh can now be invoked as following:

```
HUGENODE=0 NRHUGE=5 ./scripts/setup.sh
HUGENODE=1 NRHUGE=3 ./scripts/setup.sh
```

This will allocate 5 hugepages on node0,
and 3 hugepages on node1. If HUGENODE
param is not specified, the setup.sh will
operate just like it used to.
