minigbm: gralloc0: Allow lock_ycbcr for HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED
We can use lock_ycbcr as a way to partially work around the format resolve
problem - with the assumption that if lock_ycbcr succeeds, the
android_ycbcr struct returned describes a YCbCr 4:2:0 image, we can
query gralloc for the format instead of hardcoding one statically.
BUG=b:32077885
TEST=Camera preview renders correctly on Poppy.
