Fix Data Saver settings preference crash on Lenovo Zuk devices

The Data Saver settings menu is crashing for Lenovo Zuk devices
due to findViewById returning null. Since we don't use the title
in the PreferenceCategory, make the DataReductionStatsPreference
a Preference and set the widget layout resource dynamically. Also,
set the preference to not be selectable so that it does not have
dividers and cannot be clicked.
