Loading JNI libraries in an APEX

To load JNI libraries in an APEX, libnativeloader relies on
jni.config.txt file which contains available JNI libraries for
APEX namespaces:

  com_android_foo libfoo_jni.so:...
  com_android_bar libbar_jni.so:...

This file is generated by linkerconfig.

Bug: 143733063
Test: cuttlestone boots
      (For now, no behavioral changes because jni.config.txt is empty)
