fix: map bizhawk's ares to its n64 core only

BizHawk embeds ares as Ares64, its N64 core, whose 64DD IPL its own
FirmwareDatabase declares. Mapped to the whole ares profile, it pulled
thirty systems into the BizHawk pack and made slots accuse
FirmwareDatabase.cs of a wrong MSX.rom it never declared for ares.
