usb: gadget: g_webcam: Send color matching descriptor per frame

Currently the color matching descriptor is only sent across the wire
a single time, following the descriptors for each format and frame.
According to the UVC 1.5 Specification 3.9.2.6 ("Color Matching
Descriptors"):

"Only one instance is allowed for a given format and if present,
the Color Matching descriptor shall be placed following the Video
and Still Image Frame descriptors for that format".

Add another reference to the color matching descriptor after the
yuyv frames so that it's correctly transmitted for that format
too.
