Rebaseline virtual/android/fullscreen/parent-flow-inline-with-block-child.html

This test has been marked as [ Failure ] for a long time. As a matter of
policy, if a test output is undesirable we should open a bug for it and expect
the undesirable result, instead of marking the failure in TestExpectations and
expecting the desirable result.

Actually, the non-virtual test suite already expects the undesirable output.
I don't remember why virtual/android is expecting the desirable one.
I suspect it slipped in the many reverts/retries of crbug.com/240576.

Anyway, the main point of the test was that we don't crash.
