Stop indexing location metadata.

Browse Source 
The new ACCESS_MEDIA_LOCATION permission is designed to protect
the location metadata of items the caller doesn't own, but we can't
easily perform partial filtering of metadata from returned Cursor
objects based on per-row ownership, so we're forced to outright stop
indexing and returning location metadata via queries.

Apps can still easily obtain location metadata using ExifInterface.
