Subject: [PATCH] ISO: Fix argv[0] being set to a garbage value

- Due to GetCallbacks().resolve_path behaviour being reverted in a prior
commit, resolved_path will not have the path to the game executable.
This causes issues when setting argv[0] to the game executable path and
apparently breaks some games which may rely on this value.
