Justin Yun 5e03586365 Include static lib information for the snapshot modules
snapshot modules require the list of static libs to find the NOTICE
files for the snapshot modules.
snapshot binaries must include static_executable property to check if
non static binaries have libc as a static lib.

Bug: 190690041
Test: Check NOTICE for libaudiopreprocessing.so built from snapshots.
