Add NixOS test for QGIS and QGIS-LTR. This test creates QGIS vector memory layer containing Nix snowflake. This proves that application can successfully start and Python bindings are working. By default, Python script is executed in non-interactive mode and QGIS is closed after script is finished. This script can be also executed interactively by running following command: ``` nix-build -A qgis QGIS_TEST_INTERACTIVE=True ./result/bin/qgis --code pkgs/applications/gis/qgis/test.py ``` In this case, QGIS is not automatically closed.
