fix: remove virtual package libasound2 from Ubuntu dependencies

- Remove libasound2 and libgtk-3-0 runtime packages that are causing virtual package conflicts
- Keep only development packages (libasound2-dev, libgtk-3-dev) which provide the necessary headers
- This resolves "Package 'libasound2' has no installation candidate" errors on Ubuntu
