v4l2object: Use default colorimetry if that in caps is unknown

Browse source 
Some streams have unknown colorimetry in caps, but v4l2object sets
default values for each primaries. It will cause check colorimetry
fail when do gst_v4l2_video_colorimetry_matches().

To fix this, need to keep the unknown colorimetry in caps same as
the default value set by v4l2object.
