BuildRequires: sparse

[Roland McGrath]

I've updated extras^H^H^H^H^H^HFedora devel sparse to 0.3 and built it in
Koji.  I have no clue if magic is required to get it into the tag used for
new builds' dependencies.  The following ought to be adequate to tweak the
kernel spec to use it rather than build it (assuming the old spec crap
wants to stick around conditionally for FC-6 copies).
