TestFileFdsAreInitialised and TestSerialFdsAreInitialised were added
to ensure handles passed to os.NewFile were not added to the runtime
poller. This used to be problematic because the poller could crash
if an external I/O event was received (see #21172).
This is not an issue anymore since CL 482495 and #19098.
