compositor-fbdev: Drop intermediate shadow buffer

Currently the fbdev compositor has its own shadow buffer when rendering
with pixman, causing the following copies to occur:

[pixman shadow buffer] -> [fbdev shadow buffer] -> [fbdev hardware]

As the pixman render already does all output translation when
compositing the intermediate shadow buffer really isn't needed, so drop
it.

As a side-effect this fixes updating the fbdev hardware for outputs not
starting at 0x0.
