Kinoite: Keep spectacle & a subset of plasma-nm-*
    
    - Spectacle is not yet available as a Flatpak
    - plasma-nm-openconnect, plasma-nm-openvpn and plasma-nm-vpnc are common
      VPN options so keep them installed by default. The other ones are
      either less common or insecure and will work fine as overlayed
      packages.
