Test to see if nix-daemon is running already 

A user had an install, uninstalled it via the instructions, and found their nix broken.

The issue was based around nix-daemon already running.

I tried to be very smart around searching their launchctl files:

  $ grep -ri nix-daemon  ~/Library/LaunchAgents /Library/LaunchAgents /Library/LaunchDaemons /System/Library/LaunchAgents /System/Library/LaunchDaemons

but then couldn't figure out how to write out (nicely) commands for uninstalling
or unloading them based on their name, and also couching the instrunctions in a
bit of doubt so we don't piss off some poor mac admin because their users just
deleted some important launchd files.

Nix seems to be partially installed, because the nix-daemon is
