Install built version in libres in komodo PR test

Python tests in the komodo PR tests have not been running
against the python code in the PR. This PR fixes that by adding
the python files in the build folder to PYTHONPATH and updating
LD_LIBRARY_PATH so the correct .so files are used when running
the tests.
