ci/rpmostree: Bump to 2019.4
The vmcheck tests in 2019.3 fail because of an SSH control socket issue
on overlayfs. This is fixed in 2019.4[1]. That has some other changes
such as using Python 3 in tests. The package dependencies have been
synced from the rpm-ostree CI for that.
Unfortunately, this is no longer a totally representative test of f29
since it has 2019.3 in updates. But that's the price you pay for
exercising someone else's CI from your own CI.
