Convert paths to lower filesystem paths during setupAppDir

Making FUSE request from vold is risky because the FUSE daemon may be
down and vold could get wedged.

Additionally, the FUSE daemon only responds to requests with matching
user id paths, i.e requests on /mnt/user/0/emulated/10 will fail.
So if vold (running as user 0) makes a request on
/storage/emulated/10, it really means /mnt/user/0/emulated/10
which will fail if it gets to the FUSE daemon.

TODO: Fix the lower filesystem paths to support devices without
sdcardfs
