fix: one core name per RetroPie package

The platform scraper kept lr-dosbox-pure as dosbox-pure, which matched the standalone DOSBox Pure Unleashed profile, while the target scraper wrote dosbox_pure. Both now read core_name(), and platforms/retropie.yml is rescraped at its pinned revision 46128cd2: only the libretro core names change, and six Unleashed files leave the RetroPie manifest.
