RFR: 8335344: test/jdk/sun/security/tools/keytool/NssTest.java fails to compile [v2]

[Fernando Guallini]

> There is a compilation issue in the test **test/jdk/sun/security/tools/keytool/NssTest.java** because the [HumanInputStream](https://github.com/openjdk/jdk/blob/master/test/jdk/java/security/testlibrary/HumanInputStream.java) class was moved from keytool/KeyToolTest.java to a library class in this [PR](https://github.com/openjdk/jdk/pull/19790) for reusability. NssTest depends on KeyToolTest.java, therefore it will also need to import HumanInputStream from the test library.
