File arguments added to `std.Build.Step.Run` with e.g. `addFileArg` are not necessarily passed as absolute paths. It used to be the case that they were as a consequence of an unnecessary path conversion done by the frontend, but this no longer happens, at least not always, so these tests were sometimes failing when run locally. Therefore, the standalone tests must handle cwd-relative CLI paths correctly.
