RFR: JDK-8189608 Remove duplicated jni.h

[coleen.phillimore at oracle.com]

This looks great.  There's also jvm.h too, which is a little more 
different but shouldn't be.

Did/could you make this change in the jdk10/hs repository since it's 
primarily hotspot files?   I can't tell from the webrev.

Thanks,
Coleen
