fix(privacy): "Remove Photo Metadata" also covers emoji/sticker packs and badges (#332)

Custom emoji and sticker images, pack avatars and power-level badge
images were uploaded with their EXIF intact (GPS location, timestamp),
although they are published to every member of the room or space. Route
those three pickers through a new useStrippedFilePicker, which applies
the same stripImageMetadata as attachments and avatars.

Fixes #332
