nixos: Don't enable Docker by default
Regression introduced by c94005358c.

The commit introduced declarative docker containers and subsequently
enables docker whenever any declarative docker containers are defined.

This is done via an option with type "attrsOf somesubmodule" and a check
on whether the attribute set is empty.

Unfortunately, the check was whether a *list* is empty rather than
wether an attribute set is empty, so "mkIf (cfg != [])" *always*
evaluates to true and thus subsequently enables docker by default:

$ nix-instantiate --eval nixos --arg configuration {} \
    -A config.virtualisation.docker.enable
true

Fixing this is simply done by changing the check to "mkIf (cfg != {})".

Tested this by running the "docker-containers" NixOS test and it still
passes.

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 https://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-18.09 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-18.09

For pull requests, please rebase onto nixpkgs master.

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