tests: Fix and execute Obsoletes Python tests

The test script was added in commit
b8eab33, but never plugged into meson
build script. As a result it was never executed.

This patch registers tests/ModulemdTests/obsoletes.py test script to the
test suite and fixes the script to use properties of Glib
introspection correctly.
