Get rid of a test error on Windows caused by r60417

* test/testunit/test_parallel.rb (teardown): this code seems to allow
  `Errno::EPIPE` from @worker_in.  in such case, `close` may also raise the same
  exception.
  I'm not confident in this conclusion and still doubt that we should revert
  r60417 instead of this commit or not.
