In the cases where I've looked at the underlying log, this seems to
be in the migration/multifd/tcp/plain/cancel subtest.  Disable that
specific subtest by default until somebody can track down the
underlying cause. Enthusiasts can opt back in by setting
QEMU_TEST_FLAKY_TESTS=1 in their environment.

We might need to disable more parts of this test if this isn't
sufficient to fix the flakiness.
