Add android version guard to ASensorManager_getInstanceForPackage

This function is added to header file since 2015 but the corresponding
function is not exported through libandroid.map file until O. Thus,
it make sense to gate the usage to ANDROID_O and forward.

ASensorManager_getInstance is deprecated accordingly.
