<Swing Dev> [11] RFR JDK-8198693:Update ProblemsList for mac

[Prasanta Sadhukhan]

Hi All,

Please review the problem list updation for mac to weed out the test 
that are failing at least once in few iterations.
I tested on mac 10.13.3. With this problem list, the test failures and 
errors are nearly zero apart from 2-3 tests that are failing intermittently.

Bug: https://bugs.openjdk.java.net/browse/JDK-8198693
webrev: http://cr.openjdk.java.net/~psadhukhan/8198693/webrev.00/

Regards
Prasanta
