Remove Privileged Installer preference when appropriate.

Browse Source 
Fixes #817.

As discussed in #817, this preference is not useful on Android >= 5.0.
As such, the preference should just be removed. However, it should stay
if the privileged installer is already installed (e.g. via update.zip or
included as part of the ROM).
