Eventually, netplay will be able to use the host's NAND, but this could still be useful in some cases; for TAS it definitely makes sense to have a way to avoid using any preexisting NAND. In terms of implementation: remove D_WIIUSER_IDX, which was just WIIROOT + "/", as well as some other indices which are pointless to have as separate variables rather than just using the actual path (fixed, since they're actual Wii NAND paths) at the call site. Then split off D_SESSION_WIIROOT_IDX, which can point to the dummy NAND directory, from D_WIIROOT_IDX, which always points to the "real" one the user configured.
