feat: re-profile hatari at libretro 5092994

Pins move to libretro/hatari 5092994 and hatari/hatari 90949cf. The port now reads floppy.raw from the system directory (floppy_sound.c:146-186), documented as an optional user sample. Upstream decodes IPF without capsimage, the icon block moved by four lines, and the launcher file names leave the tos.img note for the platform layer.
