PATCH v2 1/1 fbgrab: add patch fixing pixel format report

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.

No changes in the payload. Only added Upstream-status (Adrian) and adjusted subject line (Thomas).
