Bind mount Android/ directory in FUSE.

For apps seeing the FUSE filesystem, we want to bind-mount the Android/
directory to the lower filesystem. The main reason for this is game
performance - Android/ contains both OBBs and app-private external data,
and both are heavily accessed during game startup. This is a pretty
straightforward bind-mount on top of /mnt/user.

Bug: 137890172
Test: Running the following:
df /storge/emulated/0 ==> /dev/fuse (FUSE)
df /storage/emulated/0/Android ==> /data/media (sdcardfs)
Test: atest AdoptableHostTest
