Update config.xml

deleted the following lines because I was getting an error:

 <!-- Disable stock OTA components if installed -->
    <string-array name="config_disabledComponents" translatable="false">
        <item>com.google.android.gsf/com.google.android.gsf.update.SystemUpdateActivity</item>
