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

Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
