handle AOSP 10 Runtime changes

[c3ph3us]

support android 10 changes:

In Android 10, the ART build system creates the Runtime module in two variants: release and debug (contains additional diagnostic and debugging tools). The release version is installed on user builds and the debug version is installed on userdebug and eng builds. When a device boots, apexd mounts the Runtime module under /apex/com.android.runtime.

Native libraries
Android 10 refactors native libraries that support the Managed Core Library. Several dynamically linked libraries (for example, libcrypto, libexpat, and zlib) that were previously shared with other parts of the platform are now duplicated so that the Runtime module has its own copies loaded into the runtime linker namespace. Dynamically linked native libraries provided by the Runtime module are in /apex/com.android.runtime/{lib,lib64}.

Android 10 moves the libnativebridge library to the Runtime module as this library is tightly coupled with libnativeloader and the Bionic C libraries that are part of the Runtime module.
