maliit-framework-qt6: fix build error

Got this error while building maliit-framework:

|   File "/home/marc/mnt/yocto-kde/build/tmp/work/core2-64-poky-linux/maliit-framework-qt6/2.3.1/recipe-sysroot-native/usr/share/glib-2.0/codegen/utils.py", line 22, in <module>
|     import packaging.version
| ModuleNotFoundError: No module named 'packaging'

Make sure that the 'packaging' python3 module is indeed available when
buildind the recipe.
