Tests: Update for changes to upstream ninja development version

Account for:

* commit `8f47d5aa33` (Remove `-w dupbuild` completely, always error
                       on duplicate edges, 2023-11-29)
* commit `4d98903d4c` (Improve misleading error message when an output
                       is defined multiple times, 2023-12-06)
