Subject: [PATCH] travis: switch to building inside containers

Travis host images are quite outdated, so the builds will now use containers
instead. By default there's a build for Arch Linux (using base/archlinux:latest
image) and Fedora (using official fedora:latest).

Builds are done using extra/travis-build script.
