RFR: 8337723: Remove redundant tests from com/sun/security/sasl/gsskerb [v4]

[Fernando Guallini]

> There are 3 manual GSS-API/Kerberos tests that require a manual setup and were added to the problem list years ago:
> 
> - com/sun/security/sasl/gsskerb/**AuthOnly**-> Verifies that both client and server have completed the authentication process.
> - com/sun/security/sasl/gsskerb/**NoSecurityLayer** -> Attempts to use wrap and unwrap to demonstrate that these operations should not be allowed without a negotiated security layer.
> - com/sun/security/sasl/gsskerb/**ConfSecurityLayer** -> Demonstrates the use of the security layer by wrapping and unwrapping messages on both client and server sides.
> 
> These tests need manual setup of a KDC environment, service/user principals, keytabs, JAAS configuration, and script adjustments. All that is time consuming and error prone. These do not fail if configured properly.
> 
> In contrast, the automated test sun/security/krb5/auto/**SaslBasic** already covers these scenarios and sets up the KDC with the necessary principals **automatically**, no manual setup is required. This class starts a simple KDC with one realm, several typical principal names, generates krb5.conf and keytab files, and setup a JAAS login config file.
>  
> I've enhanced SaslBasic to include additional wrap/unwrap checks with and without a security layer. As a result, the 3 manual tests and their associated files are now redundand and can be removed, as they no longer provide additional value.
