[media] gspca_vc032x: Fix wrong bytesperline 

I found a problem on vc032x gspca usb webcam subdriver: "bytesperline"
property is wrong for YUYV and YVYU formats.
With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for
pixel format conversion, the result is a wrong jerky image.

Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).
