Rename one method of run_work_thunk() to run_work_thunk_remotevalue(); this fixes a JET error around matching methods for run_work_thunk(...)

This fixes the following JET error:

```
  │┌ run_work_thunk(rv::Distributed.RemoteValue, thunk::Bool) @ Distributed /workpath/Distributed.jl/src/process_messages.jl:79
  ││ no matching method found `run_work_thunk(::Bool, ::Bool)`: Distributed.run_work_thunk(thunk::Bool, false)
  │└────────────────────
```

(cherry picked from commit 5fc61b4)
