RFR: JDK-8203364: Some serviceability/sa/ tests intermittently fail with java.io.IOException: LingeredApp terminated with non-zero exit code 3

[Gary Adams]

This proposed change allows a wider range of IOExceptions to be observed
when a LingeredApp is being shutdown. It may not be just a 
NoSuchFileException.
Botton line - if the lock file doesn't exist at the time the IOException
is observed then the main application is terminating the test sequence
and LingeredApp should end normally.
