v4l2object: complete colorspace info in debug log

The desired colorimetry is logged with all parameters (colorpsace,
range, matrix, and transfer function), but of the values actually
set by the driver, only colorspace is logged. Complete the debug
log message to display all colorimetry parameters:

  Desired colorspace is 8:1:1:1
  Got format of 640x480, format YU12, nb planes 1, colorspace 8

->

  Desired colorspace is 8:1:1:1
  Got format of 640x480, format YU12, nb planes 1, colorspace 8:0:0:0
