.ci: ovn-fake-multinode-tests: Run containers with apparmor=unconfined.

Commit 407a942 ("ci: Bump the Ubuntu image to 24.04.") already did
that for unit tests and system tests running in containers.  We should
also do it for the containers that run as part of the
ovn-fake-multinode-tests to avoid AppArmor permission issues.
