ansible: osmocom-jenkins-slave: osmocom_build_deps: install osmo-python-tests for py2 and py3

The osmo-python-tests will be used to test vty commands.
The old python2 package are only required to test old images because
the current master is only supporting python3.
Installing both doesn't conflict because the python site-packages are
different for the two version.
