List of stub libraries from system (and bionic APEX) is currently managed in static file. This change generates the list at build time and adds to the system config so linkerconfig can use it. Bug: 172889962 Test: Build cuttlefish and confirmed list is generated in /system/etc/linker.config.pb Change-Id: Ie0400e9d1098b0de19c6a7c25f261384aadde0a3
