hw/xen: Register framebuffer backend via xen_backend_init()
Align the framebuffer backend with the other legacy ones,
register it via xen_backend_init() when '-vga xenfb' is
used. It is safe because MODULE_INIT_XEN_BACKEND is called
in xen_bus_realize(), long after CLI processing initialized
the vga_interface_type variable.
