xfree86: append, not prepent, new input devices to xf86InputDevs.

Browse Source 
If devices are prepended to the list, their wake-up order on resume is not the
same as the original initialisation order. Hot-plugged devices, originally
inited last, are re-enabled before the xorg.conf devices and in some cases may
steal the device files. Result: we have different devices before and after
suspend/resume.
