Preparing to enabling Inproc launcher tests as presubmit

The plan:
1. Skip all tests that fail in inproc mode on CF (this CL)
2. Observe postsubmit and make sure no inproc tests are failing or too
flaky on CF
3. Enable presubmit
4. Switch to skipping tests from step 1 only for inproc presubmit;
they'll start failing in postsubmit
5. Gradually make all tests pass and not flaky and enable them back on
presubmit
