Subject: [PATCH] Issue when argv[0] is usb1:/... on Wii

When RA dol file launched from Wiiflow, getcwd return nothing, dirs[DEFAULT_DIR_CORE] is empty and RA "info", "autoconfig",.... dirs are on root /
This seems to be because argv[0] is starting with "usb1://...dol" (maybe incompatible libfat)
This patch allow to default dirs[DEFAULT_DIR_CORE]  on Wii to the dirname of the DOL in such cases.
