Problem: Travis is no longer free for FLOSS projects

Solution: switch to Github Actions

Travis recently started enforcing credits for OSS projects without
any funding. While it is possible to get free credits, it is a manual
step that involves contacting customer support via email and asking to
add them, every week. While this does not require money, it requires
something far scarcer: volunteers time.

Drop Travis and migrate to Github Actions.
