Fix client shape handling 

The functions awful.client.shape.update.bounding and .clip handle both
the client's shape and the shape set by Lua. However,
awful.client.shape.update.all only handles the shape set by Lua and
ignores the client's own shape. This can easily be noticed with xeyes.
When update.all ran last and you move around xeyes, the wallpaper behind
it is moved along, because it is not actually outside of the window.

Fix this by partly reverting 1a5f6b7ad2 and having update.all just
call the other two functions again.
