core: fix packages-file-list.txt after an incremental buildHEADmaster
The package instrumentation step 'step_pkg_size' is populating the files: output/build/packages-file-list.txt output/build/packages-file-list-staging.txt output/build/packages-file-list-host.txt by comparing the list of files before and after installation of a package, with some clever tricks to detect changes to existing files etc. As an optimization, instead of gathering this list before and after each package, where the 'after-state' of one package is the same as the 'before-state' of the next package, only the 'after-state' is used and is shared between packages. This works fine, except at the end of the build, as explained next. In the target-finalize step, many files will be touched. For example, files like /etc/hosts, /etc/os-release, but also all object files that are stripped, and all files touched by post-build scripts or created by rootfs overlays. This means that the 'after-state' of the last package does not reflect the actual situation after target-finalize is run. For a single complete build this poses no problem. But, if one incrementally rebuilds a package after the initial build, e.g. with 'make foo-rebuild', then all changes that happened in target-finalize at the end of the initial build (the 'after-state' of the last package built) will be detected as changes caused by the rebuild of package foo. As a result, all these files will incorrectly be treated as 'owned' by package foo. Correct this situation by capturing a new state at the end of target-finalize, so that the 'before-state' of an incremental build will be correct. Note: the reasoning above talks about packages-file-list.txt and target-finalize, but also applies to packages-file-list-staging.txt/staging-finalize and packages-file-list-host.txt/host-finalize.
