nixos/iftop: add module
This patch is heavily inspired by bd0d8ed807d29faa3deee96bafcbbd76c8fa4060 which added
a setcap wrapper for `mtr` in order to allow running `mtr` without
`sudo`. The need for the capability `cap_net_raw` that can be registered using
`setcap` has been documented in the Arch Wiki: https://wiki.archlinux.org/index.php/Capabilities#iftop

A simple testcase has been added which starts two machines, one with a
setcap wrapper for `iftop`, one without. Both testcases monitor the
bandwidth usage of the machine using the options `-t -s 1` once, the
machine with setcap wrapper is expected to succeed, the `iftop` on the
machine without setcap wrapper is expected to return a non-zero exit
code.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels git://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-18.03 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-18.03

For pull-requests, please rebase onto nixpkgs master.

NixOS Linux distribution source code is located inside nixos/ folder.
