GH-9294: Set permissions to target file on rename

* GH-9294: Set permissions to target file on rename

Fixes: #9294

When the `deleteSourceFiles` property of `FileWritingMessageHandler` is `true`, the `chmod` is not set on the target file.

* Fix `FileWritingMessageHandler.handleFileMessage()` logic to `setPermissions(resultFile)` after `move` operation

**Auto-cherry-pick to `6.3.x` & `6.2.x`**

* * Set only `OWNER_READ` permission for file in unit test
