feat: FBNeo stopped looking in per-type subdirectories

The BIOS search dropped the arcade and consoles subdirectories under
both the rom directory and system/fbneo. Seven places to put a BIOS ZIP
became four, and both profiles still documented the old list, which is
the kind of thing a user follows.

fbneo's gba_bios.bin also cited a line in the middle of a battery
allocation; its RomDesc entry, which carries the name and the crc32, is
at 538.
