RFR: 8257505: nsk/share/test/StressOptions stressTime is scaled in getter but not when printed

[Stefan Johansson]

Please review this small change to print the correct stress time for tests using `StressOptions`.

Quite recently the `getTime()` method on `StressOptions` was changed to scale the stress time using the JTREG timeout factor. See: [JDK-8252522](https://bugs.openjdk.java.net/browse/JDK-8252522)

The `printInfo()` method was left using the raw `time` member and will thus output a different time from the one actually used. This change fixes this by using the getter. For consistency the other values are fetched by the getters as well.
