fb: disable navigation bar camera button if widget carousel is enabled

Beside that the animation which starts when dragging the camera icon
to the left is broken if the user has enabled carousel animation like
tablets it does not feel natural even when we use the right animation for it.

So diable the camera button in this case and allow only swiping the camera widget on carousel mode

fb: Keyguard disable challenge drag down on slimpin/simpuk screen

On simpin, simpuck and as well account change screen it does not make
any sense to give the user the abillity to drag down the challenge to show
the widget maximized (neither if widgets are enabled or disabled)
Reason: simpin/simpuck widget is not shown due of security reasons
and on account change the next expected behaviour is that the user gets a new
setup. So it does not make in this case as well sense

Just check for current securityscreen selection to block this behaviour. As
well move the enable/disable code to a proper place
