Subject: [PATCH] test: fix debug-signal-cluster after da update

The cluster children are hitting breakpoint at `cluster.onread` and
hanging on a Semaphore wait now. This prevents them from disconnecting
gracefully. Considering that the test is checking different thing, the
cluster children needs to be force killed from the grand parent process.
