BLD: Speed up up Travis jobs by running on container-based infrastructure

All jobs currently run on Travis's legacy infrastructure - which supports sudo.
The newer container-based infrastructure is faster, but doesn't allow sudo.

This patch
 - sets sudo=false for all jobs, except the chroot job
 - uses Travis's apt addon to install all packages
 - installs eatmydata for all jobs to reduce disk IO
 - removes the tmpfs workaround for chroot builds
