abduco: report pixel sizes to child processes that use ioctl(0, TIOCGWINSZ, ...) 

Add the ws_xpixel and ws_ypixel fields to the IPC packets so that abduco
can properly respond to ioctl() requests for the screen size.

This enables terminals such as "kitty" to display images inside of an
abduco session.
