changefeedccl: deflake tests that expect frequent span-level checkpoints

In a recent commit, the interval at which change aggregators would
flush their frontiers to the change frontier was decoupled from
the span-level checkpoint interval (which is configurable via a
cluster setting). This caused some tests that only set the cluster
setting (and not `min_checkpoint_frequency`) to a low value to
sometimes flake. This patch updates all such tests to also configure
the `min_checkpoint_frequency` option.

Release note: None
