Bug #9629: Remove badly-licensed neomagic kdrive files.

Licensing issues of these files include:
- They claim to be licensed under the GPL, yet we haven't allowed that in the
  xserver repository in the past.
- They refer the user to the top of the tree for GPL license text, yet it isn't
  there.
- They claim to be derived from the (MIT-licensed) ati kdrive code, yet don't
  follow the licensing terms of those files.
(cherry picked from commit 87295b66a972a2bd194a79af6aa4f715018fcded)
