Code review request: 7151062: [macosx] SCDynamicStore prints error messages to stderr

[Weijun Wang]

Please take a look at

    http://cr.openjdk.java.net/~weijun/7151062/webrev.00/

There is spurious output to stderr from SCDynamicConfig reading. These 
cases can be simply debugged by looking at the scutil output and there 
is no need to print anything in Java. Therefore just remove them.

Noreg-cleanup.

Thanks
