Remove Xorg-specific extensions from non-Xorg miinitext

miinitext.c had a completely separate codepath for non-Xorg servers,
which included tests for Xorg-specific extensions such as
XFree86-VidMode, which were external even to the Xorg DDX.  So we can
just remove them, and the associated #undefs.
