If the system is using sdcardfs, the sdcard daemon exits after mounting.
If it's using FUSE, the sdcard daemon runs until we go to unmount.
Bug:
37638548
Test: Run "adb shell ps | grep -w Z" with sdcardfs enabled.
The sdcard daemon should not be listed.
Run again with sdcardfs disabled. The daemon should be
running, and vold should not be stuck waiting on it.
