RFR: JDK-8073328: Incremental build of gensrc broken

[Erik Joelsson]

I realize that I missed a couple of my own notes on the original review 
for JDK-8073152. Here is an update webrev where I address those points 
as well.

* Remove unused variable CHARSET_EXTENDED
* Remove use of undefined variable $(CHARSET_EXTENDED_DATA)

However, I opted not to add all the java source files in the source 
directories $(CHARSET_EXTENDED_JAVA_DIR) and $(CHARSET_EXTSRC_DIR) as 
prerequisites. I don't think it would be correct.
