iotests/129: Actually test a commit job
Before this patch, test_block_commit() performs an active commit, which under the hood is a mirror job. If we want to test various different block jobs, we should perhaps run an actual commit job instead. Doing so requires adding an overlay above the source node before the commit is done (and then specifying the source node as the top node for the commit job).
