Minor adjustments to battery.el on Android

Browse source 
* src/android.c (android_query_battery):

* java/org/gnu/emacs/EmacsService.java (queryBattery19)
(queryBattery): Reorder items in value for consistency with
Fandroid_query_battery.

* lisp/battery.el (battery-status-function): Select
battery-android only when android-query-battery is present.
(battery-android): Return temperature and correct values of
power source constants.
