ro: read Switch 2 NRR hash lists where they are

Switch 2 NRRs carry 3072-bit keys and signatures, so the fields after
them (program id, size, kind, hash list offset and count) sit 0x180
bytes later than in a Switch 1 NRR: hash list offset and count at 0x4c0,
hashes from 0x4d0 (Kirby Air Riders, Minecraft, Mario Tennis Fever).
RegisterModuleInfo read signature bytes as the hash count: Kirby Air
Riders read 51 GB of "hashes" (host memory ran out), Minecraft threw
bad_alloc and the process ended.

Read the fields at the Switch 2 offsets for Switch 2 processes, and
reject an NRR whose hash list does not fit inside it.
