RFR 8200101: sun/security/krb5/auto/Renewal.java fails intermittently

Hi All,

Please review fix for following issue:

JBS bug: https://bugs.openjdk.java.net/browse/JDK-8200101

Webrev: http://cr.openjdk.java.net/~bgopularam/8200101/webrev.00/

It was found that test failure happened due to test machine slowdown, so 
fixed the issue by increasing the time interval. I have validated the 
change with repeated run on multiple platforms and found no issues.

Thanks,
Bhanu
