oeqa/concurrencytest: Remove invalid buffering option

Fix warnings from oe-selftest -j:

/usr/lib/python3.10/os.py:1030: RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used
  return io.open(fd, mode, buffering, encoding, *args, **kwargs)

Remove the option since it clearly doesn't do much.
