[PATCH v10 2/4] cat-file: make the options mutually exclusive

We only parse the options if 2 or 3 arguments are specified. Update 'struct option options[]' to use OPT_CMDMODE rather than OPT_SET_INT to allow only one mutually exclusive option and avoid the need for checking number of arguments. This was written by Junio C Hamano, tested by me.
