Do not check for root privileges

[ioj]

If I remember correctly, using a promiscuous mode on an interface may be enabled for unpriviledged users by a kernel option (or was it ACL? don't remember). Please research it if you can and if my statement is true -- remove that root check.

Proper group permissions would also be way to run namescore by non root.
I am not checking root anymore.
