Migrate from Travis to Papr (formerly redhat-ci)

It's extremely difficult to maintain a CI testing envornment when
it's base is an ancient Ubuntu-based distro that doesn't keep
pace with upstream kernel features and fixes.  Switch to Papr,
which allows testing based off of very-modern Fedora releases.
