After experimentation with a test theme (on the latest trunk), this is
the only rule that will actually work and not break the UX of the
custom-background screens.

Custom-background is simply not compatible in any way with specifying
a background in the style.css file. Style.css files must not contain a
background-image attached to body in if they are using the
custom-background functionality.
