test/integration: use default API groups in test apiserver

The goal is to make the test apiserver behave as much as kube-apiserver as
possible. This ensures that tests are as realistic as possible out-of-the-box.
If a test needs a special setup, then that should be visible in the test
because it passes additional flags or options.

One historic deviation from that goal was enabling all API groups. That
change (from 7185624688) gets reverted and tests
which happened to rely on this get updated.
