Subject: [PATCH] ut1999: fix library search paths on x86_64-linux

Without the change the game fails to start as it fails to find it's
shared objects as:

    $ NIXPKGS_ALLOW_UNFREE=1 nix build -f. ut1999 && ./result/bin/ut1999
    Object not found: Class Render.Render
    History: UObject::SafeLoadError <- UObject::StaticLoadClass <- UGameEngine::Init <- InitEngine <- main
    Exiting due to error

After the change the game starts without problems.
