v4l2: v4l2_camera_proxy: Fix v4l2-compliance support for extended formats
Fix the following v4l2-compliance error:
fail: v4l2-compliance.cpp(652): !(caps & V4L2_CAP_EXT_PIX_FORMAT)
Simply add V4L2_CAP_EXT_PIX_FORMAT to capabilities in querycap.
In addition, populate the necessary fields in struct v4l2_pix_format to
support extended pixel formats in try_fmt and g/s_fmt, and clear the
reserved field for enum_fmt.
