[12] RFR of JDK-8209768: Refactor java/util/prefs/CheckUserPrefsStorage.sh to plain java test

[Brent Christian]

Hi, Amy

So one difference from the original test is that the process that 
creates the preferences store is still active at the time that the 
preference is checked.  I don't know if this is material to what is 
being tested or not.

It would be more similar to the original test to keep 
CheckUserPrefFirst.java and CheckUserPrefLater.java, and have the new 
CheckUserPrefsStorage.java behave more like the original script and just 
launch CheckUserPrefFirst and CheckUserPrefLater in sequence.

That way the preference store is created and written to, then that 
process exits before a new process checks the written store.

Other opinions?

Thanks,
-Brent
