PPC: Fix quik bootloader on New World Macs

Currently quik assumes a fixed load-base of 0x3f4000, and only worked on Old
World Macs because of a special exception in bootcode_load.c. Since quik seems
to be the only user of %BOOT known to date, widen the check to all Apple
machines as per conversation with Alex. PReP machines will continue to use the
standard value of load-base as normal.
