Java version DRY-ness.
Suffix java packages with version.

If not suffixed, Puppet's pkgdmg provider won't
ever upgrade once we bump java version.

E.g. Puppet creates "cookies" for version 7u45:
/var/db/.puppet_pkgdmg_installed_jdk-7u45.dmg
/var/db/.puppet_pkgdmg_installed_jre-7u45.dmg
Don't bother with JCE, it never updates the policy files.

I think because JRE policies are on disk with root:wheel
ownership, and Boxen has no powers to overwrite these
files from ice.zip.
