dix/configure: remove null root cursor option 

The default behavior of the server is to start with an invisible root cursor.
Be such cursor invisible or inexistent (null), in the end it doesn't matter -
for the user. The content on screen will be the same. Besides, there's no
difference, in terms of performance, whether such cursor is invisible or
simply null. The paths that both take inside the server are roughly the same.

Therefore create a null root cursor becomes irrelevant.
