SARIEN ONLY: Revert "vboot: remove workaround in diagnostics UI"

This reverts commit f64f7d170a516b96e90e47bd741a7258f203a744.

In order to be compatible with the current cr50 firmware this change
will make the user confirmation screen not wait for power button
release and instead only check when it is pressed.
