gnu: matplotlib: Add gtk3 backends and optional dependency. Adjust inputs.
* gnu/packages/python.scm (python-matplotlib, python2-matplotlib): Add gtk3 backends with the necessary inputs and a 'configure-environment' phase. Add the optional 'python-pillow' dependency. Move 'python-pyparsing' from 'inputs' to 'propagated-inputs' as it is required at run time.
