[9front] [PATCH] riowctl and $wctl are no more, update man pages

[unobe]

Back in September, we removed riowctl (`{git/export
87160cbfcf926fd0a9f04e8113a16c2a0c7e252d} ) and $wctl.  I had used
riowctl for one of my scripts and so was puzzled by its absence.
Here's a patch to update the documentation.
