[SPARK-3948][Shuffle]Fix stream corruption bug in sort-based shuffle
Kernel 2.6.32 bug will lead to unexpected behavior of transferTo in
copyStream, and this will corrupt the shuffle output file in sort-based
shuffle, which will somehow introduce PARSING_ERROR(2), deserialization error
or offset out of range. Here fix this by adding append flag, also add some
position checking code. Details can be seen in
[SPARK-3948](https://issues.apache.org/jira/browse/SPARK-3948).
