Harden /mnt/pass_through permission bits
It previously had 0755 permission bits
With such permissive bits, an unauthorized app can access a file using
the /mnt/pass_through path for instance even if access via /storage
would have been restricted.
It is now 0700
TODO: Change ACL for /mnt/user from 0755 to 0700 in vold only when
FUSE flag is on. Changing it with FUSE off breaks accessing /sdcard
because /sdcard is eventually a symlink to /mnt/user/0/primary
Test: adb shell ls -d /mnt/pass_through
