[Thomas:
 - Update to version 5.47.
 - Instead of selecting network-manager, depend on it, it avoids
   replicating all its complicated dependencies, and it's pretty
   obvious if you want to use network-manager that you need network
   manager.
 - Needs Qt5Dbus support, so added a select BR2_PACKAGE_QT5DBUS, and
   propagated the corresponding dependencies.
 - Add missing dependency on qt5base in
   KF5_NETWORKMANAGER_QT_DEPENDENCIES
 - add hash for license file.]
