packaging: include `windows-curses` on Windows

packaging: include `windows-curses` on Windows

Otherwise the interface degrades to the old hunk selection method on Windows
when `ui.tweakdefaults=1`.  I've been using this for a couple of months without
any issues, other than it seems to toggle off edit mode for the terminal when
run through MSYS.  Using cmd.exe seems to work fine.
