RFR: 8371383: Test sun/security/tools/jarsigner/DefaultOptions.java failed due to CertificateNotYetValidException [v2]

[Hai-May Chao]

> The `DefaultOptions.java` test may fail as the current system time is before the signing certificate NotBefore time, when jarsigner tool validates it in `CertificateValidity.valid()`. Please review the fix in this test to avoid such intermittent timing problem. Thanks.
