Fix absolute import issue in py3

As of 577f2a95e4f01c58a0a4f4ccb3b70d9c048b626e in osmo-ci, the
contrib/jenkins.sh isused forinstallation. This causes the issue with
python3 because test coded use absolute import by default.

Fix this by adding relative path and import from ../osmopy to make
sure test code uses the current module and not the one which might be
already installed in the system.
