networkmanager: Allow NetworkManager and wireless together

Browse Source 
When NetworkManager is configured to not manage all interfaces, it's
perfectly fine to have the rest be managed by the standard nixos
wireless scripts.

I use
  networking.networkmanager.unmanaged = [
    "*" "except:type:wwan" "except:type:gsm"
  ];
to control everything using networking.wireless except for the mobile
LTE modem which only works with NetworkManager.
