Commit 72c64ce02268d0e497e3c8866c00a2b3b9eb5962 in osv.git moved
runjava.jar from /java to /usr/lib/jvm/jre/lib/ext.
We need to do the same also for the openjdk8 and openjdk8-fedora
modules.

Found and patched by Ryozo Yamashita <yryozo@gmail.com>.
The original patch message:

"Fix runjava.jar's location to avoid ClassNotFoundException for io.osv.OsvSystemClassLoader."

Unfortunately, it seems there's still more to do - with openjdk8-fedora,
I'm still getting errors.
