OMAP3: added debug parameter for force video rotation

For devices that don't have sensors for detect rotation, added a property,
"debug.video.force_rotation" to test encoding rotated video.

Given value, 0, 90, 180 or 270 will replace original degrees which
MPEG4Writer::writeCompositionMatrix received. If you want turn off this
feature set negative value, like -1 to the property.
