v4l2object: fix ARIB_STD_B67 colorimetry unmatch issue

bypass check the below GST_VIDEO_TRANSFER_ARIB_STD_B67 type because kernel do not support it. GST_VIDEO_TRANSFER_ARIB_STD_B67 is cast to GST_VIDEO_TRANSFER_BT2020_12 type in gst_v4l2_object_get_colorspace

i can not find ARIB_STD_B67 in kernel document
