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.
