Need reviewers and comments: 6989472: Provide simple jdk identification information in the install image

[Kelly O'Hair]

A revised proposal...

Still called "jdk.release".
But if people really think "jdk.properties" sounds ok, at least the  
names are unique and won't conflict.

A Linux 64bit build should result in a jdk.release file that looks  
something like:

jdk.os.name = Linux
jdk.os.version = 2.6
jdk.os.arch = amd64
jdk.java.version = 1.7.0
jdk.vm.cfg.files = jre/lib/amd64/jvm.cfg
