Allow symlinks to be used in vold managed fstab entries

With device-tree kernels the sysfs path for SD cards varies depending on
device-tree layout and the actual card used. It is therefore impossible
to specify the sysfs path for the device in fstab.

However, there exists a symlink to the device which is created under a
generic path like '/sys/block/mmcblk0/device'. To use such a path with
vold we need to convert the symlinked path to the real path, which this
patch does.
