nl-link-set: Add --state option

Browse Source 
I modified the nl-link-set.c file to be able to set the interface up or
down. I joined the patch.
With the new nl-link-set binary I can set the tap interface down.
I am working with Ubuntu 12.04 LTS 64bits and the libnl and libnl-route
packages built from libnl3-3.2.3 from ubuntu reprositories.
