fix caps to avoid videoconvert bug in 1.8 which corrupts data

Browse Source 
Previous way of creating caps left invalid colorimetry field 0:0:0:0,
which combined with a bug present in GStreamer 1.8 led to GRAY16_LE data
being corrupted when converted to GRAY16_BE (or vice versa). Current
method will properly initialize colorimetry field, avoiding this problem
in 1.8.
