UMSDOS symlink fix

[Delbert Matlock]

Enclosed is a one line fix for symlinks under the UMSDOS filesystem.  Under
stock 2.4.7 (and 2.4.7-ac4), if you create a symlink the last letter of the
original file will be left off the link.  This will fix it.

Now, if I can just get the blasted thing to mount as root.
