Mount direct boot apps obb dir after fuse is ready.
- Remove bind mounting Android/ code as we want to bind mount obb dir
for each process instead.
- Set property "vold.vold.fuse_running_users" as an array of user id
for which fuse is ready to use.
- After fuse is ready for a user, fork a background process in vold
to bind mount all direct boot apps for that user so its direct boot
apps obb dir will be mounted to lower fs for imporoved performance.
