Title: ftp: Fix root path validation for upload directory

The ftp door can be configured to use a static root rather than the user's
root path. If the static root is not a prefix of the user's root directory,
the door should only allow access to the upload directory. The logic that
enforces this was broken, resulting in such upload attempts failing.
