Move gitea partial clone test

This moves the gitea partial clone test from our setup playbook into
testinfra/test_gitea.py. We should avoid asserting too much state and
behavior in the ansible as it makes the split between testinfra and
ansible more confusing. To address this we move this behavior check into
testinfra where it belongs.
