[PATCH] config: fix CONFIG_LFS option

The help text says that if you select CONFIG_LBD, then it will automatically
select CONFIG_LFS.  That isn't currently the case, so update the text.

- Get rid of the cruft in the help text mentioning CONFIG_LBD

- Tell unsure users to select CONFIG_LFS.

- Remove the `default n'.
