RFR: 8308801: update for deprecated sprintf for libnet in java.base

[Xue-Lei Andrew Fan]

Hi,

May I have this update reviewed?

The sprintf is deprecated in Xcode 14, and Microsoft Virtual Studio, because of security concerns. The issue was addressed in [JDK-8296812](https://bugs.openjdk.org/browse/JDK-8296812) for building failure, and [JDK-8299378](https://bugs.openjdk.org/browse/JDK-8299378)/[JDK-8299635](https://bugs.openjdk.org/browse/JDK-8299635)/[JDK-8301132](https://bugs.openjdk.org/browse/JDK-8301132) for testing issues . This is a break-down update for sprintf uses in libnet in the java.base module.

Thanks,
Xuelei
