Hide "Magnify with button" if no navbar is shown
Devices without a software-rendered navigation bar will be unable to
use "Magnify with button" as no accessibility button trigger for
magnification can be shown.
In this case, we hide the setting by preventing
MagnificationPreferenceFragment from showing the list of mag
modes, instead launching directly into the PreferenceFragment for
"Magnify with triple-tap"
