RFR: 8276654: element-list order is non deterministic [v3]

[Andrew Leonard]

> Fixes: https://bugs.openjdk.java.net/browse/JDK-8276654
> 
> A intermittent problem with the make dependencies means the jdk.javadoc element-list-.txt generation can remove the src defined element|package-list-<7,8,9,10>.txt files.
> Recreatable by using --with-jobs=1 causing jdk.javadoc "gendata" to always occur after "java" module build dependency.
> This fix puts a dependency of jdk.javadoc-java on jdk.javadoc-gendata to avoid this.
