Fix broken build

Summary:
Ubuntu 17.10 is reaching End Of Life (EOL) according to https://wiki.ubuntu.com/Releases, and it looks like support is already dying, as the Travis build has been broken for a while.

This changes the Ubuntu version to 16.04, which will reach EOL in 2024, and makes the appropriate changes to make the `docker build` command work.
