Intermittent v9.18 build fails on Fedora COPR buildsys, always in `netmgr_test` ?

The netmgr unit tests are not meant to run fully in the CI as some of it are time sensitive.
You might want to set the CI=true environment variable to reduce the set of the netmgr unit tests to just the more reliable subset.
