Revert "Swap Ctrl and switch_numeric keys"

This reverts commit b85b67c.

The Ctrl key was too hard to use in the new position, especially in
combination with arrows or backspace.

Leave the switching key in the numeric layout however, where the Ctrl
key is not very useful. Put Ctrl on the top-right because bottom-right
is where the switching key is in the other layouts.
