feat: a platform package can differ from upstream

bundled describes the emulator's own release, and a platform package can differ both ways: Batocera's hcl package installs the binary alone and sends users to fetch the data, while its blueMSX core package copies the machines and databases beside the core. not_bundled_on and installed_on name those platforms, and the builder reads them through one rule.
