OOBE: Fix default focus for Enterprise enrollment screen

Focusing element marked as "focus-on-show" is done by oobe-dialog's
show() method. MultiStepBehavior triggers this method for elements
marked as for-step, but enrollment_screen used legacy layout where
each oobe-dialog was additionally wrapped in the <div>, and for-step
was set on the enclosing div instead of oobe-dialog.
As a result, show() was not called on corresponding oobe-dialog upon
step switch, and default focus was not set
