RFR 8075575/8075576: 2 com/sun/security/auth tests failed in certain env

Please review the change at

The test checks for certain English text in the output, and cannot find 
if running in another locale. Tests now forced running in English.

I've tried modifying the tests to check for localized texts returning 
from ResourceBundle.getgetBundle().getString(). The test is not easy to 
read and in one test MessageFormat.format() needs to be called. I 
abandon this attempt and choose the current fix.

Thanks
