Auto merge of #43129 - Ophirr33:master, r=alexcrichton

Updated docker images to share scripts

Attempts to resolve #42201. I managed to pull out five scripts (android-base-apt-get, ubuntu16-apt-get, make3, rustbuild-setup, and crosstool-ng). Let me know if there's more I can do or if I should change some names.
