We're propagating the plugin flags by importing from another Nix
expression file, which in turn exports the Nix path to the wrapper. This
causes that the store path isn't referenced in the wrapper and the path
isn't recognized by scanning the wrapper script (only those already
referenced at build time are).
So let's add the activated plugins to the buildInputs of the wrapper.
