Update NetlinkSocketTest to handle RTM_GETNEIGH{TBL} restrictions

Modify testBasicWorkingGetNeighborsQuery to handle the case where
sending RTM_GETNEIGH{TBL} messages is not allowed.

Add test BasicWorkingGetAddrQuery, which performs a simple RTM_GETADDR
request, as a smoke test for when sending RTM_GETNEIGH{TBL} is not
allowed.
