mrtg: add 2.17.4

- The Multi Router Traffic Grapher
- You have a router, you want to know what it does all day long?
- Then MRTG is for you. It will monitor SNMP network devices and draw
- pretty pictures showing how much traffic has passed through each interface.

nixos: Remove torify module

'torify' now ships with the tor bundle itself; and using torsocks is
recommended over tsocks (torify will use torsocks automatically.)

nixpkgs: remove tsocks

tsocks is old, and users should be using torsocks these days instead.

nixpkgs: torsocks 1.3 -> 2.0.0

Additionally, this fixes 'torsocks' using the 'which' executable as a
dependency.

nixpkgs: tor depends on torsocks

This may seem strange, but tor distributes its 'torify' wrapper which in
turn attempts to use torsocks to bridge a connection, meaning 'tor'
users out the box may want it to work.

nixos: rewrite torsocks module

Rather than trying to override the 'torsocks' executable in $PATH, the
new module instead properly configures `/etc/tor/torsocks.conf` and puts
the normal `torsocks` executable in $PATH so it can work out of the box.

As a bonus, I think this module actually works now, because the torsocks
configuration has changed a lot from when this was written, it seems...

nixos: overhaul Tor module

This overhauls the Tor module in a few ways:

  - Uses systemd service files, including hardening/config checks
  - Removed old privoxy support; users should use the Tor Browser
    instead.
  - Remove 'fast' circuit/SOCKS port; most users don't care (and it adds
    added complexity and confusion)
  - Added support for bandwidth accounting
  - Removed old relay listenAddress option; taken over by portSpec
  - Formatting, description, code cleanups.
