[BUG] - Node fails to start because `DBLocked` is thrown

**External**

**Summary**

In a recent run of [antithesis](https://github.com/cardano-foundation/antithesis) we got an interesting failure: One of the nodes (out of a cluster of 5) crashed with the following error messages:

```
DbLocked "/state/lock"
cardano-node: The db is used by another process. File "/state/lock" is locked
```

According to antithesis' logs, it seems this happened when the node was _restarted_ after having been killed.

**Steps to reproduce**

We only had one occurence of this error so it seems very hard to reproduce 😅
I suspect this happens because the file was not properly removed when the node stopped as there's no guarantee it's instantaneous when using file-based locks.

**Expected behavior**

Not sure

**System info (please complete the following information):**
