minigbm: mediatek: use the HW_VIDEO_ENCODE padding for camera preview

Since CL:3515652, preview under photo mode no longer uses hw video
encoder. This results in the wrong padding set in minigbm. Make camera
preview mode to use the original padding by detecting the
GRALLOC_USAGE_HW_COMPOSER (BO_USE_SCANOUT) flag.

BUG=b:224698291
TEST=check camera preview on krane
