Apparently MPL hard requires Pillow now: broke Staging:H without it (ipython)
Will remove explicit Pillow requirement in python-control, python-mplcursors

- Require Pillow

- Work on unit testing
  * Move architecture selection to bcond definition at top of 
    specfile. This makes it clear in the OBS web UI that the test
    flavor is only built for x86_64 and aarch64
  * do not build everything a second time during check (in-place)
  * instead use new subpackage testdata wich contains the baseline
    images created at regular build time
  * use pytest-xvfb and %pytest macro 
    (buildroot path actually not required)
  * tidy test skip definitions
  * add python-gobject-Gdk to pass the gtk3 backend testso
- include version for obsoletes -qt-shared (rpmlint warning)
- move some cairo files to backend packages
- remove python2 transition requirements mock and six
- update matplotlib-setup.cfg
