RFR (S): 8223015: Cleanups for zipfs tests

[Lance Andersen]

Hi Christoph,

Thank you for doing this.  Overall the changes look good.

A few minor thoughts

ZIpFSTester.java  - 537:  Given you removed the method variable, I would tweak the printf string to make it a bit clearer that what the output its.

JFSTester.java and MultiReleaseJarTest.java -  I had the opposite feeling that having a jarfs subfolder adds clarity and moving MulltiReleaseJarTest.java might be the better way to go.  It helps separate specific tests which are using the JarFileSystem from the ZipFileSystem especially as we add more, keeping things cleaner.

Best
Lance
