[Buildroot] [PATCH/next 2/2] support/testing: update python-gobject test

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

Because gobject-introspection is now a dependency of python-gobject, the test
must be updated.

 - Change TestPythonPy2Gobject to TestPythonPy3Gobject as
   gobject-introspection requires python3.

 - Refactor test_python_gobject.py to no longer inherit the
   TestPythonPackageBase class, as this class uses a base config that does not
   support gobject-introspection.

 - Update sample_python_gobject to use Glib to find the path of sh.
