Subject: Use existing CRIU packages in CI setup

For all in testing involved distribution a new enough CRIU exists as a
package.

Fedora provides CRIU packages directly. For CentOS/RHEL there is a COPR
with the latest CRIU version and for Ubuntu there is a PPA for the
latest CRIU version. Let's use these packages and fall back to building
from git if necessary.
