RFR(S): 8198655: test/lib/jdk/test/lib/apps/LingeredApp shouldn't inherit cout/cerr

[Chris Plummer]

Hello,

Please help review the following:

https://bugs.openjdk.java.net/browse/JDK-8198655
http://cr.openjdk.java.net/~cjplummer/8198655/webrev.00/webrev/

In the end there were two issues. The first was that the 
pb.redirectError() call was redirecting the LingeredApp's stderr to the 
console, which we don't want. The second was that nothing was capturing 
the LingeredApp's output and sending it to the driver app's output (jtr 
file). These changes make all the LingeredApp's output end up in the jtr 
file.

Tested by running all tests that use LingeredApp.

thanks,

Chris
