Fix ws_stdio_unlink so it works properly on WIndows for all Unicode filenames.

- Essentially: ws_stdio_unlink would fail trying to delete
   any path\filename containing a Unicode character which could not be mapped
   to the "system codepage" (ie: to a character encoded with a value of 1-255).
   For example: ws_stdio_unlink was not able to delete a path\filename 
   containing the character U+210B.
- The problem: A copy/paste of the wrong (non-Windows) portion of the GLib 
  g_unlink code was done when file_util.c was created.
- The solution: replace the ws_stdio_unlink code with the correct code
   copied from the Glib g_unlink function.
