Sanity testcase generates SELinux policy just for one container
"fedora:latest". Testcase should test generating SELinux policy also for
Fedora Rawhide container, RHEL universal base image {7,8} and centos containers
Fix sanity test to pass on Fedora Rawhide and Fedora 30. Changes are
related to missing 'nc' command in container for which SELinux policy is
generated.
Check that udica can create policy for both podman and docker
containers. Check that generated policy can be loaded. Check that
generated policy provides required access.
