Subject: stty: only print supported options for combined options

* src/stty.c (usage): Don't reference unsupported options,
in the combined options descriptions.
* doc/coreutils.texi (stty invocation): Adjust for the
new order of the 'sane' and 'raw' combined options.
Also add -iutf8 to the 'sane' list.
