main.c: tell bionic_translation the load from anywhere in the app_data_dir

Browse Source 
Facebook implements its own native library unpack mechanism called SoLoader,
which loads native libraries from app_lib_dir/files/decompressed/libs.spo.
The libraries are loaded by absolute path, but bionic_translation needs
to know that this path may contain bionic libraries.
