[Test Failure] Socket timeout for AOF test

[madolson]

Error

sock56048fcc87c0 => (SPAWNED SERVER) pid:38170 - tests/integration/aof.tcl

We are seeing a fairly consistent failure like https://github.com/valkey-io/valkey/actions/runs/12919448042/job/36029989392#step:8:6146.

In this case, the client connecting the AOF server is hanging after starting the process but before executing the test. We can see that Turning appendonly on and off within a transaction finished, so it must be failing on Test cluster slots / cluster shards in aof won't crash which is the test that comes after. I really don't have a great read on this, but there seems to be a few occurrences . Another example is https://github.com/valkey-io/valkey/actions/runs/12940498740/job/36094850711#step:8:6290.

@enjoy-binbin I see you added the test, 80fcbd3. Maybe you have some thoughts on it.
