libcamera: v4l2_videodevice: Make V4L2PixelFormat constructor explicit

To achieve the goal of preventing unwanted conversion between a DRM and
a V4L2 FourCC, make the V4L2PixelFormat constructor that takes an
integer value explicit. All users of V4L2 pixel formats flagged by the
compiler are fixed.
