kanshi: Fix transform change between vertical and normal docked mode

Since I have two configurations for my dual-screen desktop setup, with
one having the two screens side-by-side and the other having the left
screen vertically rotated 90 degrees, I need two different kanshi
setups.

The vertical setup is called 'dockedvert' and is the default when the
two screens are detected. The horizontal setup is only called 'docked'
and can be switched to manually. Before, it would not correctly revert
the left screen from its vertical 90 degree rotation when going from the
vertical setup to the horizontal one.

So I applied the `transform` output directive but kanshi refused to
start. That is because to revert the transform into the default
horizontal position you do not use `0` but `normal` as the value.
With this fix everything works as expected.
