devel/stat(svn|cvs): run_depends on java

Java is needed to run this. So I think it makes sense to add openjdk
to the run_depends. Although when it compiled with openjdk8 it didn't
really matter what openjdk you used to run it with. Let's use JAVA_DEFAULT.

Statsvn even puts the %%JAVA%% var in files/statsvn.in so the script
wouldn't work with another JDK.

Piggyback this on the portrevision bump of my previous commit.
