libcamera: v4l2_videodevice: Take stride into account to compute offsets
When creating FrameBuffer instances, the V4L2VideoDevice computes plane offsets using minimal stride for the format. This doesn't always produce a valid result when the device requires padding at the end of lines. Fix it by computing offsets using the stride reported by V4L2.

 * The UniqueFD is a wrapper that owns and manages the lifetime of a file

 * over its ownership. The file descriptor is closed when the UniqueFD is
 * destroyed, or when it is assigned another file descriptor with operator=()
 * or reset().
