gnu: xdot: Update to 1.3.

* gnu/packages/graphviz.scm (xdot): Update to 1.3.
  [source]: Download the sources from GitHub as the PyPI tarbal is missing
  some test files.
  [arguments]: Use Gexps.  Add "start-xserver" and "set-test-environment"
  to setup test environment properly.  Simplify "wrap" phase.  Replace "check"
  phase to run "test.py".
  [native-inputs]: Add "gobject-introspection" and "xorg-server-for-tests".
  [inputs]: Add "bash-minimal", "mesa", "mesa-opencl", "python-numpy"
  and "vulkan-loader".
