Notice: Retiring vbetool in F18

[Adam Jackson]

Historically the only thing requiring vbetool was pm-utils, but that's
not been true in a nice long time:

* Fri Oct 08 2010 Adam Jackson  1.3.1-2
- Drop the vbetool dependency, suspend is only supported on KMS drivers.

That was F14 gold:

% koji -q latest-pkg dist-f14 pm-utils
pm-utils-1.3.1-2.fc14                     dist-f14              ajax

In lieu of flowers, please send patches for KMS drivers to
[e-mail].
