Use android: namespaced attributes in themes

The preference inflater prefers app: namespaced attributes, so
using those in the theme would cause them to override android:
namespaced ones defined in the preference XML. Instead we should
use the android: ones in the theme so both the android: and app:
namespaced attributes in XML will override them as expected.
