[racket] Replace user32 with GTK on WinXP

You can try setting the PLT_WIN_GTK environment variable, which will
cause "racket\collects\mred\private\wx\platform.rkt" to select the Gtk
backend under Windows.

I haven't tried it in a while, though, so I don't know how well it will
work (i.e., I gave up the idea of really supporting that mode).
