GH-8730: Fix isAcquiredInThisProcess to use localLock

The `ExpirableLockRegistry.expireUnusedOlderThan()` uses a query to the target store by mistake.
The logic of this API is indeed about the local cache for those lock instances.
We cannot effect any other processes with this cache.
And even if we remove our local instance while it is locked in other process,
that doesn't mean that on the next `obtain()` call, when we got a fresh local instance, we will be able to acquire a lock in target store.

* Fix `isAcquiredInThisProcess()` to check only `localLock.isLocked()`

**Cherry-pick to `6.1.x` & `6.0.x`**
