Replace fix permissions with fix contexts for emulated storage

Fix permissions rarely fixed anything on more recent versions of
Android and usually made things worse. Instead we will replace it
with a more dumbed down option that should fix contexts on
/data/media with a few improvements to ensure that contexts get
fixed for multiple users and on adopted storage.
