dix: (Don't) change BITMAP_SCANLINE_UNIT on Linux s390{, x}

Every other architecture sets this to 32, and I can't think of any
benefit s390 would derive from changing it.  It is, at any rate,
something the client already copes with, and the only internal code
impact seems to be some complicated math in miGetPlane, which you never
hit if you're using fb.
