Remove explicit depends on transitive pip deps
Remove explicit depends on transitive pip deps

These things were listed before we had jeepyb as its own things
(gerritlib in gerrit) and before jeepyb has pbr/requirements.txt
as it does now. With the move to pip install -U . in /opt/jeepyb,
there is no need to also ask puppet to manage these.
