Subject: [PATCH] Fix jni library name for PowerPC Architecture

Summary:
Right now, building rocksdbjava in PowerPC is broken due to JNI library name. I figured it out that "uname -m" and java's os.arch matches in PowerPC architecture. I made use of this advantage to fix the issue. More info can found from this issue  --> https://github.com/facebook/rocksdb/issues/1317
Closes https://github.com/facebook/rocksdb/pull/2040
