fix(android): rebuild prebuilt librnupdate.so with hbc transform symbols

The Android library ships prebuilt .so files (jniLibs.srcDirs = ./lib);
the previous commit changed native sources without rebuilding them, so
NativeUpdateCore.getHbcTransformVersion had no JNI implementation and
getConstants crashed the app at startup (caught by the Local Update
Merge e2e). Rebuilt all four ABIs via scripts/build-android-so.sh and
added the new symbol to verify-android-so.js so a stale prebuilt fails
verification instead of shipping.
