and Wii/sys directories if they do not already exist. This conflicts with
DolphinApp::OnInit (run after constructors) which populates the User tree
only if there isn't already something there.
Instead, set up the two directories in the Data tree.
With this change, sys/uid.sys still won't be created until the _second_ run
after a fresh install, so these file initializations should be moved out of
constructors so that they will be run after OnInit().
