Special requirements for DietPi node-red installations

Browse Source 
I wasted several hours investigating the `Error: getaddrinfo -3008` and couldn't solve it with any of the solutions proposed on this repo's issues nor on the dependency (`mdns` repo)[https://github.com/agnat/node_mdns].

In the end, it boiled down to DietP's minimalistic approach to default packages that don't even provide `avahi-daemon` out of the box (as you need to install it with `dietpi-software`) and looks like this wasn't enough for this node to work, I needed an extra prerequisite lib: `libnss-mdns`. 

I didn't try uninstalling `libavahi-compat-libdnssd-dev` or  `libudev-dev` to check if those are not needed for DietPi installations, but what solved in my case was installing this extra package.

I hope it helps someone in the future
