    Reuse fix to not rebuild if no source changes

    build-pkgs --reuse rebuilds some packages even without source
    changes. This commit fixes the checksum comparison which was
    not working correctly for all package paths.

    Test Plan:
    Pass: build-pkgs --reuse and no packages were rebuilt
    Pass: build-pkgs (no packages were rebuilt)
    Pass: make changes to 1 package and call build-pkgs to
    rebuild it
    Pass: build-pkgs --clean (rebuilds all local packages)
