Reduce dynamic symbols and strip all local ones from the Android single .so

Use a version script ("version map") that exports only the Java_* and
JNI_OnLoad symbols that the JNI machinery needs. No non-dynamic
symbols are needed (in the .so that goes into the .apk; the one kept
locally for debugging is not stripped).
