X1E: Steam: Break when enabling thunks
Enabling any thunk breaks Steam on Ubuntu 25.04 running on X1E


```sh
pressure-vessel-wrap[17113]: Internal error: /usr/share/vulkan/explicit_layer.d/VkLayer_MESA_overlay.json is not in /usr/lib/pressure-vessel/overrides/share/vulkan/explicit_layer.d

```

Without any thunk set, it works
