build: don't use a glob for java/rocksjni/*

Summary:
* src.mk (JNI_NATIVE_SOURCES): New variable, so we don't have to use
a glob in Makefile
* Makefile (JNI_NATIVE_SOURCES): Remove glob-using definition, now
that the explicit list of sources is in src.mk.

Test Plan:
  Run this:
    JAVA_HOME=/usr/local/jdk-7u67-64 PATH=$JAVA_HOME/bin:$PATH \
      make rocksdbjava
