old paths contains all entries when updating

In certains circumstances, only the base and split APKs were included in
the "old paths" list when updating the application info. Instead, this
list should contain _all_ elements, including any additional libraries
that may be added to the overall classpath.

Bug: 77342775
Test: Manual. Install a package. Install a split with --dont_kill. See that the path doesn't contain duplicate entries
