Explicitly depend on the preferred java runtime

F19 has two openjdk packages available, 1.7.0 and 1.8.0. To make sure
the yum depsolver only drags in the preferred one (and not both!)
depend explicitly on 'java' which is only provided by the preferred
runtime.

This is also recommended practice by the Fedora Java packaging docs.
