RFR: JDK-8259927: Windows jpackage installer issues

[Andy Herrick]

Remove lines in WixSourceBuilder that adds directive to rm-rf the parent dir(s) of the install-dir.  These directories get removed anyway if they are empty without these lines, and should be left alone if not empty after removing the install dir itself.
