docs-rst: conf.py: only setup notice box colors if Sphinx < 1.6
Sphinx 1.5 added a new way to change backward colors for note boxes, but kept backward compatibility with 1.4. On Sphinx 1.6, the old way stopped working, in favor of a new less hackish way. Unfortunately, this is currently too buggy to be used, and the old way doesn't work anymore. So, we have no option but to stick with boring notice boxes. One example of such bug is the notice that it is inside struct v4l2_plane, at the "bytesused" field. At least, add a notice about how to use, as maybe some day the bug will vanish.
