ci: Use custom container for Travis builds

Temporary solution. For now, this builds using a container image
based on openSUSE Tumbleweed with the current FFmpeg release.
More containers will be added (at least with git snapshots of FFmpeg
and libass), and Travis will eventually be replaced with something
we have more control over.
