RFR 8163320: JAVA_VERSION in release file should come from java.base module

[Sundararajan Athijegannathan]

Please review fix for https://bugs.openjdk.java.net/browse/JDK-8163320

jdk repo:

http://cr.openjdk.java.net/~sundar/8163320/jdk/

* JAVA_VERSION is derived from module-info of java.base

* adding quotes around all 'release' properties

top repo:

http://cr.openjdk.java.net/~sundar/8163320/top/webrev.01/

Makefile changes to avoid generating OS_NAME, JAVA_VERSION etc. - as
jlink takes care of those.

Thanks

-Sundar
