Current linker.config.pb from the package is generated with
auto-detected provide libs, but this misses require libs which can be
detected from module dependency. This change adds extra require libs to
linker.config.pb generated from system image so it can link with modules
outside of system image.
Bug: 324995772
Test: Link succeeded from Cuttlefish with soong defined system image
