RFR 8233886 : TEST_BUG jdk/java/net/CookieHandler/B6791927.java hit hardcoded expiration date

[Ivan Gerasimov]

Hello!

This test started to fail recently.

This is because it has a cookie expiration date hardcoded as 'Sat, 
09-Nov-2019 23:12:40 GMT'.

The simplest fix is to move the date forward.

I also made this test to run in the othervm mode because it modifies the 
default locale.

Would you please help review the fix?
