niimaqsrc: Output caps supports both actual bpp and bpp=16

Browse Source 
The src caps now have two structures, the first contains the actual bpp of the camera, (10, 12, or 14), and the second has the standard bpp=16. This enables the element to be used both with ffmpegcolorspace (and other elements which only accept bpp=16) but also with our elements like videolevels.
