[PATCH] hide `Try 'help' for usage' if help doestn't exist in rescue mode

[Felix Zielcke]

I think we shouldn't tell users to type `help' if the command doestn't
exist in rescue mode, i.e. minicmd isn't included in core.img
This increases the size of kernel.img for me by 28 bytes. I think it's
worth.

It's so small I don't bother to attach it:

        * kern/rescue_parser.c (grub_rescue_parse_line): Only suggest to try
        `help' if the command exists.
