android: jpeg: exif: Fix setOrientation EXIF values
The input to setOrientation is angle clockwise from the sensor
orientation, while the EXIF output values were swapped for 90
and 270 degrees.
From the EXIF spec:
6 = The 0th row is the visual right-hand side of the image, and the
0th column is the visual top.
8 = The 0th row is the visual left-hand side of the image, and the
0th column is the visual bottom.
6 should be 90 degrees clockwise, while 8 should 270 degrees clockwise.
Fix this.
As Android defines the rotation as the clockwise angle by which the
image needs to be rotated to appear in the correct orientation on the
device screen, the previous values would be correct if the input angle
was from the camera orientation. Since the correct input should be the
requested JPEG orientation, these new values are the correct ones.
