Avoid touching FUSE mounts on vold binder threads

On user unlock when persist.sys.fuse property is set,
StorageManagerService calls into vold to link the primary
volumes. Because this involves accessing a FUSE path that
has not been initialized, vold should offload this work
from the binder thread, otherwise it would wedge and the
system server would wedge causing a Watchdog trigger.

This fixes a bug where we 'link primary' twice and vold
gets wedged on system server restarts.

Bug: 140064376
Test: with the FUSE property set:
adb shell stop && adb shell start && adb shell ls /sdcard
