The `heaptrack_gui` program requires QT plugins. This works if it's included in a full install, since QT will search the users' `$PATH` for plugins; however it immediately crashes if run in a pure environment. This wraps the program to find the given `qtbase` plugins directory without requiring an impure installation. Related: NixOS#9680

The impurity for qt is necessary because the way qt searches for plugins.

Indeed, it works just fine when impurely installed and run through a user profile. However, with this change it also works when package is used outside of a nix-env.

Setting QT_PLUGIN_PATH will break integration with desktop environments: #24256 (comment)
This needs to be fixed in a central place.
