Subject: [PATCH] androidenv: fix emulator graphics acceleration

Set a default value for VK_ADD_DRIVER_FILES so the SDK's vulkan-loader
can load NixOS vulkan drivers.

libGL needs to be in LD_LIBRARY_PATH to get loaded successfully.

Tested using:
```nix
androidenv.emulateApp {
  name = "app";
  platformVersion = "36";
  abiVersion = "x86_64";
  systemImageType = "google_apis_playstore";
  configOptions = {
    "hw.gpu.mode" = "host";
    "hw.gpu.enabled" = "yes";
    "hw.keyboard" = "yes";
  };
}
```
