We have been observing intermittent issues with this test on the Autobuilder:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=15885

This is probably due to the Autobuilder being heavily loaded at the time
of the test.

The logs on the ticket above do not allow us to know which of the two
"test_default_timeout" tests is failing, so disable both with
self.skipTest().

Excerpt from `ptest-runner python3`:

  test_default_timeout (test.test_multiprocessing_fork.test_manager.WithManagerTestBarrier.test_default_timeout)
  SKIP: Test the barrier's default timeout 'skip flaky timeout test'

[YOCTO #15885]
