When verbosive, fbgrab reports pixel format. Green and blue offset and
msb_right fields are accidentally swapped there. This commit adds a patch
which straightens them up.

+Fix pixel format report
+
+When fbgrab tells about the framebuffer pixel format, blue and green
+are accidentally swapped in 'length' and 'msb_right' columns. Let's
+order everything as RGB.
