Subject: [PATCH] Send package changed for consumers of an updated shared lib

In the case that a static shared library is updated (same version code),
we should notify that the packages depending on the shared library have
changed to reflect the new paths of the shared lib.

Test: manual; update a static shared lib in place and observe broadcasts
Bug: 140129991
