Clark Boylan a09cb5acf9 Use java version independent package on Ubuntu
Different versions of Ubuntu ship with different versions of Java.
Trusty had 7, Xenial has 8, and so on. This causes problems when we
hardcode a versioned package name into our dep lists as that version may
not exist everywhere. Thankfully Ubuntu provides a default-jre-headless
package that we can use instead that maps properly onto whatever java
version is correct.
