RFR: JDK-8242522: Minor LingeredApp improvements

[Chris Plummer]

Hi Alex,

Overall it looks good, although I'm not so sure I agree with removing 
getAppOutput(). It's a generally useful utility API. Seems it is better 
off in LingeredApp.java rather than in the one test that currently uses it.

thanks,

Chris
