Yunus Shaikh fe9d31edae test(libkernel_sys): pin the AMM writers' narrowing of a wide type
The map, map direct and mtype-protect writers take type as a 64-bit
value and store it in the record's 32-bit field. That matches
sceKernelWriteModifyMtypeProtectCommand and the libSceAmpr siblings,
whose type is 32 bits, but nothing checked it. A type with bit 32 set
now has to record the same bytes as the sibling given the low 32 bits,
and the debt entry says the console's handling of such a type is not
measured.
