[XXS] RFR tier1 testbug JDK-8211180: SourceLauncherTest.java fails in JDK12 CI on Win*

[Jonathan Gibbons]

Please review a small urgent fix for a tier1 testbug issue.

It is a perennial problem, comparing golden text on Windows. This time, 
with that in mind, I was too clever by half, and proactively converted 
platform newlines in the generated output to \n, not realizing that the 
method being used for the comparison was doing the opposite, and 
converting \n in the golden string to platform newlines!

The fix is just to avoid converting newlines to \n.
