Recent motd failures

All my Ubuntu Core devices (16, but might apply to 18 as well) started to have this in the logs in the last few days:

Nov  9 15:21:21 foo systemd[3858]: motd-news.service: Failed at step EXEC
spawning /etc/update-motd.d/50-motd-news: No such file or directory

hmm, i definitely remember having added code that explicitly removes that file when we originally built core16 (it calls non-installed binaries (cuirl), connects to the internet to pull news from ubuntu.com etc etc) … smells like it sneaked back in when the build moved to the official builders by foundations … @sil2100, @slangasek ?

(i also note that my core18 images actually ship this file by default which seems like a big oversight)
