Update mctp help to be consistent with the use of IFNAME

The help information for the mctp tool alternated between using <dev>
and <IFNAME> when describing interface names. Switch to use <ifname>,
which should be more helpful than `dev <dev>` and matches the case
conventions of the other options.

Update README.md to reflect the changes and add `mctp monitor` to the
end, which had been ommitted.
