bug: non-nixos-gpu with Nvidia missing `libnvidia-egl-*.so` and Wayland libraries

### Are you following the right branch? - [x] My Nixpkgs and Home Manager versions are in sync ### Is there an existing issue for this? - [x] I have searched the existing issues ### Issue description In my home.nix I have: ``` targets.genericLinux.enable = true; targets.genericLinux.gpu.nvidia = { enable = true; version = "610.43.02"; sha256 = "sha256-MDSgVLtM33dS/43CclZMsQVROAS/9TU4lFkBsWyndGM="; }; ``` While it satisfies most GUI programs, several still have problems. For example, OBS Studio cannot capture screen, and emits such messages: ``` ... info: --------------------------------- info: Initializing OpenGL... info: Using EGL/Wayland libEGL warning: pci id for fd 27: 10de:1e84, driver (null) pci id for fd 13: 10de:1e84, driver (null) pci id for fd 28: 10de:1e84, driver (null) libEGL warning: egl: failed to create dri2 screen pci id for fd 13: 10de:1e84, driver (null) pci id for fd 28: 10de:1e84, driver (null) libEGL warning: egl: failed to create dri2 screen info: Initialized EGL 1.5 warning: Unable to open DRM render node. info: Loading up OpenGL on adapter Mesa llvmpipe (LLVM 21.1.8, 256 bits) info: OpenGL loaded successfully, version 4.6 (Core Profile) Mesa 26.1.2, shading language 4.60 info: --------------------------------- ... info: ------------------------------------------------ info: Loaded scenes: info: - scene 'Scene': info: - source: 'Wayland output(dmabuf)' (wlrobs-dmabuf) info: ------------------------------------------------ info: Device for 'Audio Output Capture' source Desktop Audio is also used for audio monitoring.
