media: v4l2-compat-ioctl32: Copy v4l2_window->global_alpha
Commit b2787845fb91 ("V4L/DVB (5289): Add support for video output overlays.") added the field global_alpha to struct v4l2_window but did not update the compat layer accordingly. This change adds global_alpha to struct v4l2_window32 and copies the value for global_alpha back and forth.
