nixos,darwin: add sharedModules and extraSpecialArgs options (#1793)

Browse source 
This allows users of the nixos and nix-darwin module to set shared modules
for all users and extra specialArgs to be available to home-manager modules.

The latter is named extraSpecialArgs just like the argument to
modules/default.nix.
This could be confusing since the the two are independent in code,
but they do mean the same thing so I think the name fits.

Darwin can now refer to the global system configuration if used as a module
through the special `darwinConfig` argument.
